The temperature dependence of dc magnetization is investigated for the rare earth chromites SmCrO (Formula presented.) and the doped compound SmCr (Formula presented.) Mn (Formula presented.) O (Formula presented.). Different from the magnetization behavior of SmCrO (Formula presented.) , temperature-induced magnetization reversals are observed in the Mn (Formula presented.) -doped compound. Moreover, low-temperature isothermal magnetization measurement indicates the magnetic ground state of SmCr (Formula presented.) Mn (Formula presented.) O (...
