Magnetic behaviour of Al and Mn substituted Gd2Fe17 compounds

摘要: Abstract We investigated the magnetic properties of Gd 2 Fe 17− x M compounds with M=Al or Mn. performed low-field magnetization measurements to obtain values for Curie temperature and high-field ( B ≤38T) on powdered samples that were free orient themselves in field applied saturation magnetization. From slope we derived R–T coupling constants n RT using mean-field approximation. find substitution Al Mn, although it reduces different ways, has only little influence intersublattice strength.
