Preparation of Sm-Fe-N by High-Pressure N2 Nitridation and Sm2Fe17 by a Diffusion Process

TbCu7-type Sm-Fe(-N) powder synthesized by low-temperature reduction-diffusion process using the Li–Ca reductant

“…5 b was not observed. Normally, kinks in magnetic curves (demagnetization curves) are caused by the presence of a soft magnetic phase such as the ɑ-Fe phase [ 38 ]. Although a trace amount of the ɑ-Fe phase remained in our powder, its effect did not appear in the magnetic curve.…”
