High frequency magneto-impedance of double perovskite $L{a}_{1.2}S{r}_{1.8}M{n}_2{O}_7$: secondary transitions at high temperatures

Radio frequency magneto-impedance measurements clearly reveal a pronounced anomaly at 260K besides the main MI transition at 125K in the double perovskite material $La_{1.2}Sr_{1.8…
