Abstract

We have investigated magnetic and magnetoelastic properties of (La0.8Ba0.2)0.93MnO3 single crystal over temperature range of 4.2-150 K in magnetic fields up to 12T. The basic magnetostriction constants of the (La0.8Ba0.2)0.93 MnO3 single crystal have been estimated using longitudinal and transversal magnetostriction measurements data, which were carried out along different crystallographic directions of single crystalline sample. The variation of magnetic domain structure in applied external magnetic field has also been analyzed using magnetization hysteresis loop measurements.
