Ra. Doroshenko et Sv. Seregin, PHOTOINDUCED CHANGES IN THE DYNAMIC MAGNETOELASTIC INTERACTION IN YTTRIUM-IRON-GARNET, Physics of the solid state, 39(6), 1997, pp. 969-971
The effect of light on the excitation efficiency and resonant frequenc
y for the fundamental mode of contour elastic oscillations of a circul
ar ferrite-garnet slab is investigated. A reduction in the dimensionle
ss parameter for the dynamic magnetoelastic coupling is observed. It i
s shown that illumination produces changes in the effective magnetostr
iction field and in the magnetic anisotropy. (C) 1997 American Institu
