    Abstract

    A considerable thermal hysteresis in magnetization and conductivity and a large magnetoresistance ratio (Δπ/π0) in excess of 80% (with applied magnetic field H = 15 kOe) over a wider temperature span (∼50 K) has been obtained in the sample of polycrystalline La0.5Dy0.12Ca0.33MnO3, indicating that a particular magnetic structure, the canted ferromagnetic structure, should be present. The metamagnetic transition from canted ferromagnetic ordering to ferromagnetic ordering is possible to occur at relatively high temperatures and under a small applied magnetic field.
