Abstract

Anisotropic magnetoresistance (AMR) in La_0.79Ca _0.21MnO₃ single crystals has been investigated. In contrast with previous studies, in our experiments AMR increases with decreasing temperature, reaches the maximum below T_C and decreases with further temperature decrease. Variations of MR while rotating the sample around the [110] crystalline direction may be associated with uniaxial magnetocrystalline anisotropy. The unusual enhancement of AMR below T_C is ascribed to changes in the magnetic domain structure revealed by magneto-optical techniques.
