Abstract
Impurity spin resonance of (Formula presented) ions doped in the one-dimensional ferromagnet (Formula presented) was investigated in a submillimeter wave region using pulsed magnetic fields at 1.7 K. As expected from the Mössbauer result, the isolated electron state of (Formula presented) with g=2.00 was successfully observed. The D values of Fe ions are found to be 0.66 (Formula presented) in a ferrimagnetic region and -0.87 (Formula presented) in a ferromagnetic region which is anomalously large and would be caused by the exchange interaction between a Fe spin and surrounding Co spins.
