【摘要】 <正> Rare earth (R)-3d transition metal (T) intermetallic compounds have potential application as permanent magnets and other novel smart materials owing to their distinctive electronic structures. Since the saturation magnetization increases with the increase in the 3d transition metal content, T-rich intermetallic compounds are the most promising candidates for new magnetic materials. For example, a series of R1-δT5+2δ compounds can be formed by substituting dump-bell T-T atoms for the R atoms in RT5 compounds with the CaCu5-type structure. For δ=1/2, which means that a dump-bell T-T atoms replaces one R atom in every two RT5 units, there form RT12-type compounds with the ThMn12-type structure.For δ= 1/3, a dump-bell T-T atom substitutes for one R atom in every three RT5 units,更多还原
