A detailed study of the electrical and magnetic properties of polycrystalline (Formula presented) has been carried out. This perovskite-type compound should be a canted ferromagnetic metal at low temperatures. The magnetization and conductivity show considerable thermal hysteresis, indicating a first-order canted ferromagnetic state-to-paramagnetic state transition. Application of a magnetic field (Formula presented) leads to a metamagnetic transition from canted ferromagnetic ordering to ferromagnetic ordering up to 95 K, and magnetoresistance (Formula presented) larger than 90% over a temperature range (Formula presented) has been observed.
