Paper Abstract

In this work, effective magnetic fields relevant to all-optical magnetic recording (AOMR) are analyzed considering, specifically, optically-induced spin-orbit (OSO) coupling and the Inverse Faraday Effect. Computing these fields with reasonable estimations of the required parameters, it is shown that OSO fields developed in typical rare earth alloys have a distribution with exterior rings of maximum amplitude in the perpendicular component, in contrast to the IFE field which has its maximum in the center. These observations may correlate to experimental observations that have revealed exterior rings in the recorded spots during the AOMR process.
