Abstract
The Mössbauer effect of a dilute impurity in Tc was measured for the first time. The isomer shift and the quadrupole splitting at room temperature are -0.02±0.01 and -0.13±0.02 mm/s, respectively. Small induced magnetic fields, -4.5±1 and -7.5±1 kOe, were found in external magnetic fields of 30 and 45 kOe at 4.2 K. This indicates that the magnetic character of Fe impurities in Tc lies in the intermediate region between magnetic and nonmagnetic. The induced field may be attributed to local spin fluctuation.
