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 La_0.5Dy_0.12Ca_0.33MnO₃, 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.
