概要
- 論文の詳細を見る
In single crystals of yttrium iron garnet irradiated with white light at 77K, a remarkable change was observed in the temperature dependence of complex permeabilities μ' and μ". Simultaneously, conspicuous double peaks of DA around 125 K (DA1) and 200 K (DA2) were found to be induced by the irradiation at 77K, with correlatiVe onset of an irreversible decrease of permeability at low temperature. Besides, the dark DA (DA3) independent of white-light irradiation was observed around the room temperature. The activation energy of DA (1,2,3) may be calculated as 0.46, 0.60,and 0.88 eV, respectively.
