Description

A new series of compounds with the ThMn12-type structure RFe11.5Ta0.5 (R ≡ Tb, Dy, Ho, Er and Lu) has been synthesized and studied by x-ray diffraction, ac susceptibility and magnetization versus temperature and field measurements. The maximum Curie temperature is for the Tb compound (TC = 576 K). Spin reorientation transitions have been observed for the compounds DyFe11.5Ta0.5 and ErFe11.5Ta0.5. A first order magnetization process has been observed at low temperature in DyFe11.5Ta0.5 and HoFe11.5Ta0.5. The importance of the metallic radius of M in the magnetic properties of RFe12-xMx (for the same rate of M substitution) is discussed. (author)
