计算小型铁磁长球体的成核场，作为其尺寸、伸长率以及施加场与球体轴之间的角度的函数。如果除了磁化卷曲和相干旋转之外没有其他切换模式，这些结果可能代表矫顽力。该计算仅对于各向同性粒子是严格的，但对于易轴平行于椭球体长轴的单轴或立方各向异性也给出了一阶近似。 (C) 1997 年美国物理研究所。
The nucleation field is calculated for a small ferromagnetic prolate spheroid as a function of its size, its elongation, and the angle between the applied field and the spheroid axis. If there is no other switching mode except for magnetization curling and coherent rotation, these results probably represent the coercivity. The calculation is rigorous only for an isotropic particle, but a first order approximation is also given for a uniaxial or cubic anisotropy whose easy axis is parallel to the long axis of the spheroid.
