ABSTRACT
Thin films of GaAs[SUB1-x]N[SUBx] were grown on insulating GaAs substrates and subjected to temperature-dependent resistivity, Hall, Seebeck, and Nernst coefficient measurements. Density of states, effective-mass values, which are calculated from the transport data, decrease from 0.084 m[SUBe] to 0.029m[SUBe] as x increases from 0 to 0.004.

    The effect of through-thickness temperature gradients in thin films irradiated by short laser pulses is described, together with its application to direct overwrite. We found by simulation that through-thickness temperature gradients become substantial when a medium is irradiated by short laser...

    FeTaCN films, prepared by using reactive sputtering, were studied for the application for soft underlayers of perpendicular media. As-deposited FeTaCN nanocrystalline films with a N[SUB2]/Ar ratio of 5% exhibited high saturation moment (B[SUBs] = 1.63 T) and low coercivity (1.4 Oe). IrMn/FeTaCN...
