Abstract
The magnetic properties (magnetic ordering temperature and magnetization) of the ferrimagnetic compounds R2 Fe14B (R = Gd, Tb, Dy, Ho and Er) and their hydrides R2Fe14BH2.5 were studied. It was found that incorporation of hydrogen into the crystal lattice of R2 Fe14B compounds substantially increases the Curie temperature and Fe-Fe exchange interactions. Hydrogenation does not practically change the intersublattice exchange field h21 and exchange field h22 within the R - sublattice. This effect can be understood as a result of the attendant changes in the unit cell volume and an electronic structure of these compounds. © 2007 Springer.
