 note = {The microstructure of the rare-earth-cobalt magnets Sm(Co0･63 Cu0･09 Fe0･26 Zr0･02)7･1 aged at 750℃, 850℃ and 900℃ was investigated by means of X-ray diffraction, optical microscope, SEM and related to coercivity of the magnets. The magnets aged at 750℃, 850℃ and 900℃ consisted of the mixture of ZRSD phase, 2-7 phase, cells of 2-17 phase surrounded by 1-5 phase boundary in grains and precipitates along grain boundaries. The cells became larger in size with aging temperature, which appeared in transient state. The magnets aged at 850℃ and 900℃ contained many stacking faults parallel or inclined at about 60-90℃ to each other which lay on pyramidal and basal planes, although the magnet aged at 750℃ contained no stacking faults. The coerdvity was the largest in the magnet aged at 850℃, which had cells with about 240 nm in diameter and proper distribution of copper. The change of coercivity with aging temperature was interpreted on the basis of modified model in which no magnetic domain walls could move through the 2-17 phase of cells., 長崎大学工学部研究報告, 14(23), pp.189-196; 1984},
