Contribution of thermal expansion in the change of the Raman active frequencies with temperature in MnBi2Te4 crystals


Raman scattering in MnBi2Te4 single crystals was studied. The contributions of phonon-phonon interaction and thermal expansion in the change of Raman frequencies with temperature have been determined.

Keywords: Raman scattering, Raman-active phonons, thermal expansion, anharmonicity, elastic modulus
