(a) Normalized ZFC/FC magnetization curves in the 10–300 K temperature range in an applied field of 40 kA m−1. (b) Field-dependent magnetization curves of the nanopowders collected using a VSM at 50 K (solid lines) and 300 K (dashed lines). (c) An enlarged view of the low-field region illustrating the difference in the coercive fields of the samples.
