Abstract
The magnetic field induced effects in the second harmonic generation (SHG) from epitaxially grown iron-garnet films have been studied. The magnetic field induced variations in the azimuthal angular dependences and the polarization diagrams of the SHG intensity are shown to be due to the linear Faraday effect. Enhancements in the SHG intensity were detected for (Bi,Gd,Fu) 3(Fe,Ga) 5O 12 iron-garnet films grown on (Gd,Ca) 3(Mg,Zr,Ga) 5O 12 single-crystal substrates with various orientations. This dependence of the SHG intensity on the magnetic field may be caused by magnetostriction effects.
