Anomalous surface impedance in reentrant ferromagnetic superconductors
Abstract
For ErRh4B4, owing to the critical spin fluctuations just above T/sub s/ (greater than T/sub c2/), the critical temperature at which surface ferromagnetism appears, the reciprocal penetration depth, lambda (-1), decreases smoothly as T decreases toward T/sub s/. For ErO 5HoO 5Rh4B4, the decrease in lambda(-1) for F greater than T/sub c2/ is very small, and lambda(-1) decreases abruptly at T/sub c2/.
