Abstract
We have observed electron paramagnetic resonance of paired spin in Rb 2 Co 0.3 Mg 0.7 F 4 at 220, 370, 693.6 and 762.2 GHz in pulsed magnetic fields and found that the g -value is different from that of single spin. It is considered that the anomalous g -value of paired spin comes from the mixing of the ground state with the excited state due to both λ L S and strong exchange interaction. The detailed analysis is discussed.Keywords
