英文摘要	The forward degenerate four-wave mixing geometry was employed to induce microstructure in an organic free radical azobenzene polymer film. Before irradiated with Ar(+) laser beams (lambda = 514.5 nm), the azobenzene organic free radical polymer exhibits magnetic isotropic measured by superconducting quantum interference device. After photo-induced microstructure, the polymer film becomes magnetic anisotropy. When the applied magnetic field H = 50 Gauss, the magnetization along the normal direction of the polymer film is M(z) = 5.5 x 10(-5) emu/g, which is larger than M(x) = 4.1 x 10(-5) emu/g in the direction parallel to the polymer film.; Physics, Multidisciplinary; SCI(E); 中国科学引文数据库(CSCD); 0; ARTICLE; 2; 240-242; 20
