A detailed study of the electrical and magnetic properties of polycrystalline La{sub 0.52}Gd{sub 0.15}Ca{sub 0.33}MnO{sub 3} 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 H=1.5T leads to a metamagnetic transition from canted ferromagnetic ordering to ferromagnetic ordering up to 95 K, and magnetoresistance ({Delta}{rho}/{rho}{sub 0}) larger than 90{percent} over a temperature range {approximately}30K has been observed. {copyright} {ital 1997} {ital The American Physical Society}
