Abstract :
Detailed microstructural characterization of magnets and homogenized as-cast alloys, which included X-ray diffraction Rietveld analysis, has indicated that the so-called platelet or lamellae phase is (SmZr)1(CoFeCu)3 with the PuNi3 structure and lattice parameters a~0.5 nm and c~2.4 nm. The structural and magnetic properties of the (SmZr)Co3 phase were investigated. The microstructure shows two phases differing in their Zr/Sm ratio. Magnetization curves for the samples (Sm0.33Zr 0.67)Co3, (Sm0.33Zr0.67)Co 2.97Fe0.03, and (Sm0.67Zr0.33)Co3 are consistent with the two-phase microstructure observed. Room temperature coercivity values of these samples are low (ap1 kOe.)
