摘要

Spinel ferrite Zn_(1-x)Co_xFe_2O_4 (0≤×≤1) (111) composition-spread thin film was epitaxially grown on an MgAl_2O_4(111) substrate by combinatorial pulsed laser deposition. Sequential deposition of the two end-compounds with monolayer-period led to the formation of solid solution with addressable composition. Point-by-point ultraviolet-visible magnetic circular dichroism and Faraday rotation angle spectra showed a significant variation with x, and the latter spectra combined with absorption spectra led to the rapid evaluation of magnetooptical performance factor as functions of x and photon energy. A significant enhancement of ultraviolet magnetooptical effect was observed by substituting a small amount of Zn (≤30at. %) for Co in CoFe_2O_4.
