Anomalous Residual Surface Conductivity in a Superconductor with Strong Spin-Orbit Coupling
J. R. Chamorro, P. Chauhan, C. Sun +10
Conventional BCS superconductors are expected to exhibit a conductivity with vanishing dissipation with decreasing temperature. While bulk physical properties measurements indicate…
Above-Bandgap Magneto-optical Kerr Effect in Ferromagnetic GaMnAs
C. Sun, J. Kono, Y. Cho +3
We have performed a systematic magneto-optical Kerr spectroscopy study of GaMnAs with varying Mn densities as a function of temperature, magnetic field, and photon energy. Unlike p…
Femtosecond Demagnetization and Hot Hole Relaxation in Ferromagnetic GaMnAs
J. Wang, L. Cywinski, C. Sun +3
We have studied ultrafast photoinduced demagnetization in GaMnAs via two-color time-resolved magneto-optical Kerr spectroscopy. Below-bandgap midinfrared pump pulses strongly excit…
Ultrafast Quenching of Ferromagnetism in InMnAs Induced by Intense Laser Irradiation
J. Wang, C. Sun, J. Kono +4
Time-resolved magneto-optical Kerr spectroscopy of ferromagnetic InMnAs reveals two distinct {\em demagnetization} processes -- fast ( ps) and slow (100 ps). Both compone…
