μSR experiments have been performed on metamagnetic PrCo2Si2 at zero field at various temperatures down to 4.2 K and at high magnetic fields up to 13 T, well above the saturation field at 4.2 K. Large changes of the relaxation rates have been observed at the critical temperatures, where the magnetic structure changes. At high field, the relaxation rates have been found to be large. This effect is considered to be due to the spin fluctuations which occur in the long-period structure phases.
