Abstract
Impurity spin resonance of Fe3+ ions doped in the one-dimensional ferr omagnet Ca3Co2O6 was investigated in a submillimeter wave region using pulsed magnetic fields at 1.7 K. As expected from the Mossbauer resul t, the isolated electron state of Fe3+ with g = 2.00 was successfully observed. The D values of Fe ions are found to be 0.66 cm(-1) in a fer rimagnetic region and -0.87 cm(-1) in a ferromagnetic region which is anomalously large and would be caused by the exchange interaction betw een a Fe spin and surrounding Co spins.
