Original Paper


The effect of temperature variation on low-field microwave absorption (LFMA) was investigated on the SmFeAs(O,F) powder sample of average particle size of ∼3μm in the superconducting region (40K). The two peaks (broad and narrow) which were reported on a pellet of the same sample (Onyancha et al., J. Supercond. Nov. Magn. 28, 2927 (2015)) are observed on the LFMA line shape signal of this powdered sample. It evidently indicates that the peaks are not necessary confined to pellet sample only. Also, the LFMA intensity is found to evolve as a function of temperature. This temperature dependence of the LFMA intensity is interpreted on the framework of effective medium theory in which coupling and decoupling of Josephson junction is considered. Furthermore, we observed an anomalous hysteresis (the LFMA signal in the forward DC field sweep is above the backward DC field sweep) which is consistent with the prediction of the two-level critical state model.
