We have studied the laser-induced high-speed remagnetization and tunneling magnetoresistance (TMR) effects in tunnel magnetic junctions (TMJ). Using magneto-optical investigations, all-optical pump and probe technique, we have studied mechanisms of the laser-induced remagnetization and shown feasibility of the high-speed laser-controlled remagnetization and resistance switching in the TMJ. It is shown that the laser-induced remagnetization is caused by the internal effective magnetic fields of the inverse magneto-optical Faraday effect and the effective magnetic field of s–d-exchange interaction between the laser-induced spin-polarized current and a lattice magnetization together with a laser-induced thermal demagnetization.

Probe Measurements

AbstractOptical pump-probe measurements were performed on planar slab waveguides containing silicon nanocrystals in an attempt to measure optical gain from photo-excited silicon nanocrystals. Two experiments were performed, one with a continuous-wave probe beam and a pulsed pump beam, giving a time resolution of approximately 25 ns, and the other with a pulsed pump and probe beam, giving a time resolution of approximately 10 ps. In both cases the intensity of the probe beam was found to be attenuated by the pump beam, with the attenuation increasing monotonically with increasing pump power. Time-resolved measurements using the first experimental arrangement showed that the probe signal recovered its initial intensity on a time scale of 45-70 μs, a value comparable to the exciton lifetime in Si nanocrystals. These data are shown to be consistent with an induced absorption process such as confined carrier absorption. No evidence for optical gain was observed.
