摘要

Some structural and magnetic properties of RFenTi and RFenTiH compounds, both of which crystallize with the I4/mmm tetragonal ThMn_(12)-type structure, are presented. The effect of hydrogen insertion on the ordering temperature and the iron sublattice contribution to the ordering of the RFe_(11)Ti phase is investigated. Then the effects of hydrogen on the magnetic properties is discussed and compared to what has been reported for other series of iron rich intermetallic compounds such as R_3Fe_(29-x)M_x, R_2Fe_(17), RFe_(13-x)M_x and R_2Fe_(14)B, RFe_2... It is shown that if similar effects including increase of the ordering temperature and of the saturation magnetization are observed for the R_2Fe_(17), R(Fe,M)_(12). R_3Fe_(29-x)M_x and R_2Fe_(17) series, very different behaviour can also be observed for other series like RFe_2 where hydrogen insertion can be detrimental to the magnetic properties.
