- 論文の詳細を見る
The relaxation mechanisms in multilevel spin system have been studied by detecting the ESR using optical Faraday rotation. Both allowed and forbidden transitions have been investigated. The steady state of the spin system is analyzed by rate equations and thermodynamical treatments. 4-spin cross relaxation processes are effective to the center line of the allowed transitions. One the other hand, the spin-lattic relaxation processes are dominant for the other lines. Saturation phenomena have been observed both for the allowed and forbidden transitions. The center line of the allowed transitions does not saturate over the microwave power range used in the experiments. The temperature and the magnetic field dependences of spin-lattice relaxation time have been measured from the transient response of the magnetiation.
