| 内容記述 | The relationship between the magnetization and magnetic moment at each Fe site in Sm(Fe 1− x Co x ) 12 compounds and their temperature dependence were investigated via synchrotron Mössbauer spectroscopy. The enhancement in the Fe magnetic moments in the Sm(Fe 1− x Co x ) 12 compounds with increasing Co content was observed at a similar rate as the increment in their saturation magnetization at 300 K. We found that the magnitudes of the Fe magnetic moments vary in a descending order: 8i > 8j > 8f, and they are independent of the Co content because the variation is caused by the magneto-volume effect. The curvatures of the temperature dependence of the Fe-sublattice magnetic moments are larger and also vary in the order of 8i > 8j > 8f because the enhancements in the exchange couplingstrength decrease in the same order. | |||||
