| Abstract: | A new type oscillatory magnetotransport phenomenon has been observed in θ-type crystals of (BEDT-TTF)2I3 at temperatures below 6 K and in the magnetic field above 3 T. The oscillation appears when the magnetic field of a fixed strength is rotated from the direction normal to the conductive two dimensional plane to a direction parallel to the plane. The period of the oscillation is described by an equation tan (θmin)=sN (s=0.39, N=0, 1, 2, 3,…), where θmin is the angle giving the position of the trough of the oscillation. The amplitude of the oscillation is primarily determined by the magnetic field component normal to the conductive plane. It is related to the temperature through the change in the resistivity 0. |
