    The complex phase transitions of SmBaMn2O6 single crystals are investigated using temperature-dependent Raman spectroscopy. Distinct anomalies associated with the charge-orbital ordering are observed in the breathing mode at 614 cm−1, which shows a pronounced enhancement at the high-temperature charge-orbital ordering temperature of 380 K and a splitting into 597 and 631 cm−1 at the low-temperature charge-orbital ordering temperature of 200 K. Furthermore, the Jahn–Teller mode at 480 cm−1 exhibits a blueshift up to 5 cm−1 below the antiferromagnetic spin ordering temperature of 175 K, indicating spin–phonon interaction with a strong coupling constant of 2.5 cm−1. The observed anomalies in phonon frequency, linewidth, and intensity near the phase transition temperatures highlight the importance of lattice–charge–spin interactions in SmBaMn2O6.

    Abstract

    Application of physical forces, ranging from ultrasound to electric fields, is recommended in various clinical practice guidelines, including those for treating cancers and bone fractures. However, the mechanistic details of such treatments are often inadequately understood, primarily due to the absence of comprehensive study models. In this study, we demonstrate that an alternating magnetic field (AMF) inherently possesses a direct anti‐cancer effect by enhancing oxidative phosphorylation (OXPHOS) and thereby inducing metabolic reprogramming. We observed that the proliferation of human glioblastoma multiforme (GBM) cells (U87 and LN229) was inhibited upon exposure to AMF within a specific narrow frequency range, including around 227 kHz. In contrast, this exposure did not affect normal human astrocytes (NHA). Additionally, in mouse models implanted with human GBM cells in the brain, daily exposure to AMF for 30 min over 21 days significantly suppressed tumor growth and prolonged overall survival. This effect was associated with heightened reactive oxygen species (ROS) production and increased manganese superoxide dismutase (MnSOD) expression. The anti‐cancer efficacy of AMF was diminished by either a mitochondrial complex IV inhibitor or a ROS scavenger. Along with these observations, there was a decrease in the extracellular acidification rate (ECAR) and an increase in the oxygen consumption rate (OCR). This suggests that AMF‐induced metabolic reprogramming occurs in GBM cells but not in normal cells. Our results suggest that AMF exposure may offer a straightforward strategy to inhibit cancer cell growth by leveraging oxidative stress through metabolic reprogramming.

    We have introduced a high accuracy version of the Yee algorithm based on nonstandard finite differences for which the error is ε∼(<i>h/λ</i>)<sup>2</sup> compared with ε∼(<i>h/λ</i>)<sup>6</sup> for the ordinary one. This high accuracy allows the use of coarse numerical grids, which greatly reduces the computational cost. Realistic two-dimensional calculations can run on a personal computer, while three-dimensional ones can run on a fast workstation. Using this high accuracy algorithm, we developed computational models and methods to simulate optical propagation in photonic crystals, and to compute their transmission spectra, and bandgap structures. In addition, methodologies were developed to accurately represent arbitrary lattice structures on coarse grids.

    We report measurements of thermopower in Pr1-xCaxMnO3 (0.33 ≤x ≤0.48). A clear anomaly has been observed at the charge ordering temperature Tco for x = 0.33,0.34,0.47 and 0.48. Negative thermopower below Tco shows that the carriers are of electron-type in the charge-ordering state of x = 0.47 and 0.48.This indicates that the hopping of eg electrons at the Mn4+ sublattice, i.e., extra Mn3+ ions, dominates the transport properties in the charge-ordering phase. Thermopower below Tco changes from negative to positive around x ∼0.35 as the eg-electron number (1-x) increases, which implies a spatial ordering of extra Mn3+ ions. The ordering of extra Mn3+ ions possibly stabilizes the 1:1 commensurate charge ordering with the wave vector of (100) with x far from the commensurate composition, x = 0.50.Thermopower is found to be significantly dependent on magnetic field. The result should be closely related to the stability of the charge ordering in a magnetic field.

    We measured dielectric spectra in the charge ordering state of Pr1-xCaxMnO3 (0.30 ≤x ≤0.50),for frequencies of 100 Hz∼15 MHz. Observed dielectric spectra were analyzed using the Debye model. The effective number of electrons (n/m) is nearly temperature independent. Dissipation, γ, drastically increases with cooling. Temperature dependence is almost the same as resistivity curve. This indicates that the hopping of polarons dominate both dc- and ac-electrical transport in the charge ordering phase. Based on the small-polaron-hopping model, x-dependent activation energy is estimated, which reaches a maximum at $x \simeq 0.33$. The γ-value decreases in magnetic fields, but does not scale with magnetization.

    I studied the colossal magnetoresistance effect of double-perovskite NdBaMn2O6 single crystal. We succeeded in the growth of a high-quality single crystal that exhibits the metal-insulator transition near 300 K. The colossal magnetoresistance of the crystal shows the resistance change more than 2 order of magnitude at a magnetic field lower than 2 T near 300 K. I revealed the insulator phase was charge-orbital ordering phase using synchrotron x-ray diffraction measurements. The colossal magnetoresistance is caused by the charge-orbital ordering melting in a magnetic field. The neutron diffraction measurement using the single crystal showed the crystal has a layered antiferromagnetic ordering phase below 235 K. In general, the layered antiferromagnetic phase does not coexist with the charge ordering phase. The competition of these phases could be caused by the high-temperature and low field colossal magnetoresistance in this material.

    I have carried out the single crystal growth of double perovskite manganites, and the measurement of the electrical and magnetic properties of these samples. In this study, I succeeded the single crystal growth of the double perovskite manganite for almost rear earths, and the observation of an anomaly of the temperature dependence of the dielectric constant at magnetic phase transition. This anomaly depend on an applied magnetic field. I think these results clearly show the strong coupling between the dielectric and the magnetic properties of the double perovskite manganite.
