Summary:The study of the magnetoconductance effect in the natural chlorophyllthin films has been presented. The natural chlorophyll films is deposited on a CuPCB substrate with a spin coating method. The results show that discrete-island type of the surface morphological was observed with Atomic Force Microscope.The measurement of the current as a function of magnetic field show that the a typical symmetrical curve of the magnetoconductance effect was obtained for the natural chlorophyllthin films sample. The rasio of the magnetoconductance effect decrease with the increase of the bias voltage. It is suggested that the recombination of the carrierschargeoccur in the present of the magnetic field.
