Hysteresis loops, \(m_{{\textrm{r}}}\), \(H_{{\textrm{c}}}\), \(H_{{\textrm{eb}}}\) for S1. (a) Hysteresis loops at various temperatures showing different shifts of the loops with temperature after field cooling at a positive field. Plot of (b) remanent magnetization \(m_{{\textrm{r}}}\), coercive field \(H_{{\textrm{c}}}\), and exchange bias field \(H_{{\textrm{eb}}}\) as a function of temperature. (c) The temperature dependence of the DC magnetization. The measurements were done on heating at different fields after zero-field cooling (ZFC) and field cooling (FC) in 5 kOe (500 mT). The CoFe saturation magnetization per unit volume estimates to \(\approx\) 2.3 \(\mu _B\)/atom at 2 K.
