Large coercivity in anisotropy compensated Tb0.3Dy0.7Fe1.95 by microstructural refinement

Creators

Description

The anisotropy compensated Tb0.3Dy0.7Fe1.95 serves as an ideal alloy system to study the effect of microstructural refinement influencing coercivity. The cast alloy was melt spun and ball milled (with and without magnetic field) to impart microstructural refinement and correlated with the development of coercivity. Coercivity as high as 6500 Oe obtained during magnetic field assisted ball milling due to fine particle size, alignment of particles and strain. Coercivity of 1000 Oe obtained during melt spinning due to fine grain size and attacking faults on account of fast cooling. A comparative study highlighting coercivity mechanisms in the samples prepared by different routes has been highlighted in this paper
