Change in Magnetic Domain Structure of Nd‐Fe‐B Sintered Magnets by Compressive Stress

SUMMARY To clarify the relationship between compressive stresses and demagnetization of Nd‐Fe‐B sintered magnets, we have examined the change in domain configuration by compressive stresses using a Kerr microscope. The magnetic domains of five kinds of Nd‐Fe‐B sintered magnets have been observed. Th...
