A sharp peak in zero-field attenuation at Tc2 and a large anisotropy of the attenuation depending on the direction of sound propagation at magnetic field above Hc2 are observed for x = 0.10. These results indicate that the screening of the spin-spin interaction due to the persistent current plays an important role in ferromagnetic superconductors.
