Hysteresis loops of initial, simply heat treated, and diffusion treated anisotropic MQA powders.
Initial magnetization curves of anisotropic MQA magnetic powders before and after the diffusion treatment.
XRD patterns of the initial and diffusion treated MQA powders.
(a) A TEM image of initial MQA material. (b) Magnified image of (a). (c) TEM image of simply heat treated MQA material at 600 °C. (d) TEM image of diffusion treated MQA material with the addition of 30 wt. % Pr68Cu32 alloy. (e) Scanning TEM image where the line scan is marked perpendicular to the grain boundary; (f) The corresponding line scan results showing elements distribution. Grain boundary regions are indicated by dashed lines.
