摘要：
We have observed electron paramagnetic resonance of paired spin in Rb2Co0.3Mg0.7F4 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 lambda-LS and strong exchange interaction. The detailed analysis is discussed.
