The results indicate that as the magnetizing field increases, both the coercivity and remanence increase sharply up to a certain high field and then slowly increase to a saturated value.
结果表明，随着磁场的增加，矫顽力及剩余磁感应强度开始时快速增大，高场后增加缓慢并趋于饱和。

Metal magnetic powder with fine particles and relative higher coercivity and remanence are ideal materials for high density magnetic recording.
金属磁粉颗粒细小，具有较高的矫顽力和剩磁，是较为理想的高密度磁记录材料。

The ferromagnetic materials which has high magnetic saturation, high characteristics of magnetic conductive and low remanence should be chosen first for the higher heat power.
