... J because of the presence of the Fe3Pt. Of cause, the kink in the magnetic curves was more evident in the samples with high Fe content. In another series of samples, we fixed the current ... example. The curve shows a typical hard magnetic hysteresis loops with high Hc. Note that, because of the limit of maximum applied field of 13.5 kOe, the curve is a minor loop. Therefore, the real ... of the samples. J is the current density; ton is the deposition time of a pulse; Fe, Pt are the atomic percent of Fe and Pt in the samples, respectively; Hc is the coercivity; Ms is the...
