Abstract:

The results are given of the investigation of the temperature dependence of the sound velocity v, internal friction Q(-1), and thermal expansion DeltaL/L of a single crystal of La0.85Sr0.15MnO3 in the temperature range from 5 to 400 K. Clearly defined singularities of the elastic properties at a temperature of charge ordering T-co approximate to 200 K are revealed. The results of X-ray diffraction studies performed at room temperature are used to determine the orientations and estimate the sizes of twins. The correlation between magnetic and structure inhomogeneities is established. Based on the results of analysis of the temperature dependence of internal friction and thermal expansion, an assumption is made of the presence in a single crystal of La0.85Sr0.15MnO3 of a structural transition in the temperature range from 15 to 60 K that has not been observed previously.
