New ferromagnetic 5:2 compounds in the rare-earth - Palladium systems

Gd5Pd2 is ferromagnetic below 335°K. The isostructural Tb5.10Pd1.90, Dy5.07Pd 1.93, and Ho5.04Pd1.96 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. © 1964 The American Institute of Physics.
