It has been shown that it is possibility to control magnetoresistance by light. The use of light-sensitive banana-shape molecules has been suggested as an engine for varying the thickness or spacer between the magnetic layers. The spacer is lled by a conducting polymer with copper-like conductivity (with inserted bent molecules), ensuring the proper interlayer exchange coupling, which is necessary for transition from a ferromagnetic to an anti-ferromagnetic ordering (and inverse) when the thickness of the spacer changes.
Keywords: magnetoresistance, banana-shape molecule, conducting polymer.
