| 内容記述 | Magnetic properties of anisotropic and isotropic SmCo5/α-Fe nanocomposite magnets with a layered structure were computer-simulated with varying the stacking period, the α-Fe fraction, and temperature. The (BH)max values of approximately 800 and 700?kJ/m3 were achieved for anisotropic magnets at 300 and 473?K, respectively. These values roughly agree with results for SmCo5/α-Fe with a core-shell structure, and the value at 473?K is much higher than that of Nd2Fe14B/α-Fe with a layered structure. For isotropic magnets, the largest H c values were obtained for the stacking periods of approximately 20 and 25?nm at 300 and 473?K, respectively. The achieved (BH)max values were approximately 300 and 250?kJ/m3 at 300 and 473?K, respectively. The behavior of H c was discussed in terms of the ratio of exchange energy to magnetic anisotropy one. | |||||
