Abstract

An observation of microstructure revealed that a laser-irradiated Nd-Fe-B target under the laser energy density above 10 J/cm2 enabled us to prepare isotropic nano-composite thick-film magnets with good magnetic properties due to a dispersed α-Fe + Nd-Fe-B structure. The formation of the structure is attributed to the etching process of a target during a deposition. Moreover, the control of composition in the nano-composite film enhanced the (BH)max value up to ∼ 130 kJ/m3.
