Abstract:
The magnetorefractive effect (MRE) in manganites has been studied within the effective medium theory. The MRE has been calculated in manganites La$_{1-x}$K$_{x}$MnO$_{3}$ ($x$ = 0.1 and 0.15) for light transmission and reflection. Good agreement with experimental results demonstrates direct relation of the MRE to the magnetoresistance and optical properties of manganites with various substitution levels. It has been shown that the MRE can exceed 10% in the near- and mid-IR region near the magnetic phase transition and can change sign during light transmission and reflection in the region of phonon modes. The results make it possible to recommend the MRE as a contactless method for studying magnetoresistive materials and for developing sensors and microelectronic elements.
