Research Abstract

In the phthalocyanine molecular conductor, the giant magnetoresistance is observed. In order to clarify the mechanism of this magnetoresistance, we performed the high precision X-ray diffraction measurement under the high magnetic field. We found that the strength of the diffuse streak having the wave number of 4k_F decreases under the applied magnetic field. If this diffuse streak is ascribed to the charge order, the giant magnetoresistance is caused by the magnetic-field-induced suppression of the charge order.
