英文摘要	A polymer containing azobenzene side groups each with an organic free radical end was synthesized. Before irradiation by an Ar+ laser beam, the polymer was magnetically isotropic. However, with the irradiation of a polarized Ar+ laser beam, the photoisomerization and reorientation of the azobenzenes took place bringing about a magnetic anisotropy in the radical containing polymer film. The magnetic anisotropy was studied by using a superconducting quantum interference device. It was found that when the applied magnetic field Happroximate to1 Oe, the magnetization M-z(H) in the direction perpendicular to the polymer film was 3.63x10(-4) emu/g, while those parallel to the polymer film were M-x(H)=M-y(H)=-1.1x10(-5) emu/g.
