内容記述 | The magnetic properties of SmCo5/α-Fe nanocomposite magnets with a core-shell structure were computer-simulated for varying particle size L, α-Fe fraction, and temperature. The structure, consisting of a hard SmCo5 core and a soft α-Fe shell demonstrated better magnetic properties than those of the inverse structure. The (BH)max value for anisotropic magnets was approximately 800 kJ/m3 at room temperature for an L value of 6.4 nm and an α-Fe fraction of 87.5%. At 473 K, the achievable (BH)max value was approximately 700 kJ/m 3. These values are comparable to and higher than those for Nd 2Fe14B/α-Fe nanocomposite magnets at room temperature and 473 K, respectively, indicating a promising potential for high-temperature SmCo5/α-Fe nanocomposite magnets. | |||||
