Abstract

We have investigated the surface impedance penetration depth, Λ, of ErRh4B4 and Er0.5Ho0.5Rh4B4 both experimentally and theoretically. For ErRh4B4, owing to the critical spin fluctuations just above Ts ( > Tc2), the critical temperature at which surface ferromagnetism appears, Λ−1 decreases smoothly as T decreases toward Ts. For Er0.5Ho0.5Rh4B4, the decrease in Λ−1 owing to spin fluctuations for T ⪆ Tc2 is very small, and Λ−1 decreases abruptly at Tc2. Theoretical values of Λ−1 are in good agreement with the data.
