Mossbauer Effect Study of Spin Relaxation in CaFe_2O_4
スポンサーリンク
概要
- 論文の詳細を見る
Mossbauer effect measurements have been made on CaFe_2O_4, an antiferromagnetic oxide which has a magnetic transition at low temperatures. It has been found that the hyperfine splitting due to the internal field for the high temperature magnetic phase is subject to motional narrowing, possibly due to the thermal fluctuation of the spin correlation between weakly interacting antiferromagnetic arrays of Fe and O atoms.
