Thermal Properties of Mn-doped LiNbO₃Crystals from Magneto-Optical Transitions

Abstract

In this study, we determine that the electron paramagnetic resonance line-width (EPRLW) is axially symmetric about the c-axis and analyze the spin Hamiltonian with an isotopic g-factor of 1.9920 at a frequency of 9.5 GHz. It should be noted that the electron paramagnetic resonance signals are Lorentzian. Our findings show that the EPRLW decreases exponentially with an increase in the temperature; i.e., its temperature dependence in the range 300-400 K obeys Arrhenius behavior, this kind of temperature dependence indicates an off-center a motional narrowing of the spectrum when Mn 2+ impurity ions substitute for Nb 5+ ions. The specific heats follow a linear dependence suggesting a simple Debye T 3 behavior.

Magneto-optical Transitions in Electron-Piezoelectric Phonon Scattering Materials Using Projected Liouville Equation

“…In our previous studies [8][9][10][11][12][13][14], we applied the EAPT theory to Ge and Si, because there are abundant experimental data on nonconfining deformation potential systems. We also compared our numerical calculation results using the EAPT theory with the existing experimental data and found them to be in good agreement with each other.…”
