Abstract
Powder samples of hexagonal Laves phase ErMn2Hx hydrides, with 0 < x less than or equal to 4.3, are characterised by X-ray analysis and SQUID magnetometry for temperatures ranging between 2 and 375 K. Structural transformations as function of the hydrogen concentration and temperature were observed. In particular, a decomposition of spinodal type has been found. It has been shown that structural transformations are reflected in the magnetic behaviour and that an increase of the Mn-Mn distance above the critical distance causes appearance of Mn magnetic moments. The analysis of the magnetic data as function of the hydrogen content, temperature and magnetic field shows that the Mn magnetic moments are antiferromagnetically coupled. The behaviour of these hydrides is compared with the properties of cubic hydrides.
