A comparison of torque-strengths in micromagnetics

In the approach-to-magnetic-saturation range, we present experimental data for the magnitude and applied magnetic-field dependence of the volume-averaged mean-square magnetostatic stray field |Hdb|^2 that results from non-zero divergences of the magnetization from within the volume of bulk samples of nanocrystalline electrodeposited Ni and Co and coarse-grained polycrystalline cold-worked Ni. The magnitude of |Hdb|^2 is compared to the volume-averaged mean-square anisotropy field Hp|^2, which arises from the combined effect of magnetocrystalline and magnetoelastic anisotropy.
