摘要:

The nucleation field for rare‐earth‐Co5particles is shown to be directly related to variations in the domain wall energy associated with an oxide layer at the particle's surface. A physical model based on the experimental results for Nd1−xSmxCo5single crystals can quantitatively describe the magnetization reversal.
