Abstract

Magnetic measurements on oriented single crystals of Ho0.5Dy0.5FeO3 grown using optical floating zone furnace provide evidence for two spin reorientations of Fe3+ magnetic sublattice viz., Gamma(4) -> Gamma(1) -> Gamma(2) at temperatures T-SR1 = 49 K and T-SR2 = 26 K. As magnetic field along c axis increases, the sample resumes Gamma(4) spin configuration and a large field is likely to disrupt the spin reorientation process. It is evident from isothermal magnetization along c axis that field induced Gamma(1) -> Gamma(4) transition is feasible within the intermediate temperature range of T-SR1 - T-SR2 and can be triggered at a critical field. Such magnetic behavior is better understood as a consequence of anisotropic effective field, modified by the application of external magnetic field. (C) 2018 Elsevier B.V. All rights reserved.
