Time resolved measurements of spin and carrier dynamics in InAs films
We report time resolved measurements of spin and carrier relaxation in InAs films with carrier densities of 1.3 1016 and 1.6 1016 cm−3 grown on 001 and 111 GaAs, respectively. We used standard pump-probe and magneto-optical Kerr effect spectroscopy at different excitation wavelengths, power densities, and temperatures. We observed sensitivity of carrier and spin relaxation time to the photoindu...

Ultrafast spin dynamics and critical behavior in half - metallic ferromagnet : Sr 2 FeMoO
Ultrafast spin dynamics in ferromagnetic half-metallic compound Sr 2 FeMoO 6 is investigated by pump-probe measurements of magneto-optical Kerr effect. Anomalous thermal insulation between spins and electrons due to half-metallic nature of this material gives rise to a very slow spin relaxation from a few to several-hundred picosecond after the optical excitation. The optically detected magneti...

Abstract. A number of time resolved optical experiments probing and controlling the spin and charge dynamics of the high mobility two-dimensional electron gas in a GaAs/AlGaAs heterojunction are discussed. These include time resolved reflectivity, luminescence, transient grating, magneto-optical Kerr effect, and electro-optical Kerr effect experiments. The optical experiments provide informatio...
