Abstract
The magnetic properties of the compound Ho2Co7 and its hydrides with hydrogen concentration 2.6 and 6 atH/mol are studied. A spin-glass-like and superparamagnetic behaviours are found for the β and the γ hydride phases respectively. Strong reductions in exchange interactions and Tc for both hydrides phases is observed.
