Hysteresis loop measurements. a Hysteresis loops for the [Dy10/Tb10]10 sample at various temperatures after field cooling in 70 kOe (7000 mT) from 300 K. The loops are corrected for their diamagnetic contributions. b Plot of coercive field Hc and exchange bias HEB (negative bias) at various temperatures. c Plot of Hc versus temperature \(T^{\frac{1}{2}}\) and its linear fit showing the maximum for the zero field cooled (ZFC) curves TF(0) = 205 K. Error bars in (b) and (c) represent standard error of the estimated field value. The plot can also be fitted with an exponential function which leads to an ambiguity regarding the phase identification
