Production of (Sm,Zr)(Fe,Co)3 magnets

“…The hysteresis loop of the (Sm 0.7 Zr 0.3 )(Fe 0.75 Co 0.25 ) 3 specimen (red lines) was wider than that of the (Sm 1-x Zr x )(Fe 0.75 Co 0.25 ) 3 (x = 0–0.2) specimens but was not smooth. Such a constrained hysteresis loop is usually observed in the specimen consisting of two magnetic phases with different coercivity [ 28 ]. This is consistent with the results of the XRD and DTA studies, indicating that the (Sm 0.7 Zr 0.3 )(Fe 0.75 Co 0.25 ) 3 specimen consisted of the amorphous and SmFe 3 phases.…”

Magnetic interactions and interface properties in Co/Fe multilayers

“…16 In order to increase the interface contribution, very thin 57 Fe layers were evaporated. The hyperfine magnetic field distribution obtained from the fitting of the Mössbauer spectra indicated that a sharp Fe concentration gradient has been formed at the interface.…”
