Excess milling resulted in degradation of the trapped field because of Tc reduction. The increased grain boundary density and electron scattering are considered to contribute to the high trapped field through quantitatively and qualitatively enhancing the grain boundary flux pinning. 展开 ...

grain boundary (GB) diffusion, while grain growth is ruled by GB migration. The abnormal grain growth at 1300 °C can be attributed to the small grain size of Ni–Zn ferrite powders, providing a large amount of activation energy for grain boundary migration. Some small pores are also ...
Crossover behavior was observed at around 350 nm Ni grain size, where a ductile and soft magnetic composite was tuned into a hard mechanical and semi-hard magnetic one. Keywords: metal matrix composite; metastable Ni–P alloy; submicrometer grain-sized materials; bottom-up strategy; mechanical ...
