摘要：
Intermetallic compounds in the series TbFe12-xMox, with nominal Mo contents, x, ranging from 1.5 to 3.5, were synthesized and examined for their thermomagnetic properties. Magnetic measurements were performed in the temperature range 5-1130 K by using a SQUID magnetometer and a Faraday balance in combination. Synthesis of interstitially carburized TbFe12-xMOxC powders by mechanical alloying with graphite and a subsequent heat treatment was attempted for the single-phase compositions between x = 2 and x = 3. The magnetic behavior of the materials (especially the coercivity) shows a number of peculiarities, which we try to explain in terms of crystal chemical and microstructural features.
