A comparison of torque-strengths in micromagnetics

Abstract 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 〈| H d b | 2 〉 v 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 〈| H d b | 2 〉 v is compared to the volume-averaged mean-square anisotropy field 〈| H p | 2 〉 v , which arises from the combined effect of magnetocrystalline and magnetoelastic anisotropy.
