Abstract

Magnetic field induced second harmonic generation (MSHG) is suggested as a nonlinear-optical readout for magnetic film-based memories: Systematic studies of the nonlinear-optical magnetic Kerr effect and MSHG interferometry are carried out for (i) magnetic rare-earth iron garnet films, (ii) Gd-containing Langmuir-Blodgett films and (iii) CoxCu1-x granular films. The magneto-induced nonlinear-optical properties of thin films being used for recording the information can be easily distinguished by the MSHG nondestructive probe. An estimation of the signal-to-noise ratio (readout error) shows an acceptable value of the magnetic contrast for this potential readout.
