New Ferromagnetic 5:2 Compounds in the Rare-Earth—Palladium Systems

Abstract

Gd₅Pd₂ is ferromagnetic below 335°K. The isostructural Tb_5.10Pd_1.90, Dy_5.07Pd_1.93, and Ho_5.04Pd_1.96 have paramagnetic metamagnetic transitions at 62°, 41°, and 27°K, respectively, and become ferromagnetic at lower temperatures with extremely high hysteresis. Energy products (B×H)_max = 20 to 26×10⁶ GOe at 4.2°K have been observed.
