Abstract

Perturbed angular correlation has been used in the investigation of HFI of gadolinium ion diluted in YIG. Static magnetic HF and static electric quadrupole HF interactions of comparable strength as well as the magnetic relaxation effects had to be taken into account in this system. The PAC methodology approach appropriate to this situation is proposed. The agreement for the room temperature data is obtained. The system at low temperatures exhibits certain anomalies, which are discussed assuming the correlation time approaches the nuclear state life time at these temperatures.
