中文摘要	a systematic investigation of crystallographic and magnetic properties of nitride r3fe29-xcrxn4 (r=y, ce, nd, sm, gd, tb, and dy) has been performed. the lattice constants and unit cell volume decrease with increasing rare earth atomic number from nd to dy, reflecting the lanthanide contraction. after nitrogenation the relative volume expansion of each nitride is around between 5% and 7%. the nitrogenation results in a good improvement in the curie temperature, the saturation magnetization and anisotropy fields at 4.2 k, and room temperature for r3fe29-xcrxn4. magnetohistory effects of r3fe29-xcrxn4 and r3fe29-xcrx (r=nd and sm) are observed in a low field of 0.04 t. first order magnetization process occurs in sm3fe24.0cr5.0n4 in magnetic fields of 2.8 t at 4.2 k. after nitrogenation, the easy magnetization direction of sm3fe24.0cr5.0 is changed from the easy-cone structure to the uniaxial. the good intrinsic magnetic properties of sm3fe24.0cr5.0n4 make this compound a hopeful candidate for new high-performance hard magnets.
