Abstract
Abstract The NMR investigation of 11B in ErRh4B4 has been performed between 4.2 and 1.2 K. The BCS like temperature dependence of T1 in a mixed state is followed by an unusual deviation below 2.4 K in the field of 2.2 kOe where a positive magnetization appears. This indicates a possible phase change from the type II/2 to type II/1 superconductor and may imply the the coexistence of the ferromagnetically ordered and the superconductive state in the small external field.
