Description

The relaxation of the μ+SR signal has been investigated for the three compounds YRh4B4, ErRh4B4 and SmRh4B4. In the non-magnetic superconducting (Tsub(c) approx. 11 K) YRh4B4, the data display a Kubo-Toyabe (gaussian) shape for zero (transverse) magnetic fields. ErRh4B4 (superconducting below 8.7 K and ferromagnetic below 1 K) shows a dominant signal with very slow relaxation. In contrast SmRh4B4 (superconducting below 2.7 K and antiferromagnetic-superconducting below 0.87 K) shows a change in relaxation from gaussian above approx. 60 K to exponential between 1 K and 4 K to two exponential signals (fast and slow) below Tsub(N) = 0.9 K. In the region 0.9 K < T < 4.5 K, the relaxation time and the asymmetry both increase with T. (Auth.)
