Abstract

The invention is based on the object of designing a method and an arrangement for manipulating domain information stored in a magnetic medium, wherein spin-polarized electric current pulses are conducted through the medium and bring about domain wall displacements on the basis of the racetrack memory method, such that a reduction of the current density and of electromigration becomes possible. The method according to the invention is characterized in that, for the purpose of reducing the current density required for domain wall displacement, the medium is illuminated with polarized pulsed laser light using the effect of a reversal of the magneto-optical gradient effect for producing a torque at the spin system of the domain walls, wherein domains which are magnetized in the plane of the medium surface are illuminated with perpendicular incidence and domains having magnetization oriented perpendicularly to the medium surface are illuminated with oblique incidence. A further essential feature according to the invention consists in the fact that the wavelength, the pulse duration and the fluence of the pulsed laser light are chosen such that the laser light does not input heat into the magnetic medium in a manner that would lead to heating of the medium in excess of the heat generated by the electric current pulses. The arrangement according to the invention is characterized by a pulsed laser source for illuminating with a polarized laser beam a domain structure which is magnetized in planar or perpendicular fashion and is present in the medium. The method and arrangement according to the invention are applicable, in particular, in the field of magnetic data storage.
