Abstract
The magnetic hardening behavior of high coercivity nanograin Sm-Co magnets has been examined through a detailed investigation into their magnetic and microstructural properties. We examined the effects of various substitution s like Zr. Fe and Cu, on the magnetic behavior. Initial magnetization and r emanence curves are characteristic of domain wall pinning type or single do main particle behavior. A correlation of results indicates that the reversa l is controlled by the pinning of interaction domain walls at Local anisotr opy minima.
