hard magnetic material การใช้

• Figure 3 : Magnetic moments at the interface of a hard magnetic material and a soft magnetic material.
• These include : bulk hard magnetic materials, high frequency materials, low-dimensional materials ( micro and nano ), nanoscale magnetic structures, magnetic non-destructive evaluation methods, and biomedical applications of magnetics.
• An "'Exchange Spring Magnet "'is a magnetic material with high coercivity and high saturation properties derived from the exchange interaction between a hard magnetic material and a soft magnetic material, respectively.
