Ultrafast spin dynamics and critical behavior in half-metallic ferromagnet : Sr_2FeMoO_6
T. Kise, T. Ogasawara, M. Ashida +3
Ultrafast spin dynamics in ferromagnetic half-metallic compound Sr_2FeMoO_6 is investigated by pump-probe measurements of magneto-optical Kerr effect. Half-metallic nature of this…

Ultrafast optical nonlinearity in quasi-one-dimensional Mott-insulator
T. Ogasawara, M. Ashida, N. Motoyama +7
We report strong instantaneous photoinduced absorption (PA) in the quasi-one-dimensional Mott insulator in the IR spectral region. The observed PA is to an even-p…
