Elastic properties of La1−Sr MnO3 single crystals
Source abstract
Abstract
Abstract Longitudinal sound velocity V l and internal friction Q −1 were measured in ferromagnetic single crystals of La 1− x Sr x MnO 3 , x =0.15, 0.20, and 0.25 and La 0.75 Ba 0.25 MnO 3 by composite oscillator method at a frequency of about 100 kHz. Increase of Sr content results in increase of V l and weakening its temperature dependence. Giant thermal hysteresis connected with transition between orthorhombic and rhombohedral phases is found. The strong peak of Q −1 due to relaxation process is observed in La 0.75 Sr 0.25 MnO 3 .
