Inverse transverse magneto-optical Kerr effect

It is shown theoretically that a static in-plane magnetic field is generated in a ferromagnetic film by p-polarized light obliquely incident on the film. This phenomenon can be called the inverse transverse magneto-optical Kerr effect. The femtosecond laser pulse of peak intensity of 500 W/{μ}m² generates in nickel an effective magnetic field of about 100 Oe. The value of the effective magnetic field can be increased by more than an order of magnitude at the surface plasmon-polariton resonance excited in smooth metal dielectric structures or in plasmonic crystals.
