Rhombohedral phase of pressure-temperature treated C[sub 60] polymer was investigated by resistivity, X-ray diffraction and ESR measurements. The pure rhombohedral phase of C[sub 60] polymer displays highly anisotropic electrical properties, and the conductivity in the polymerized 2D plane exhibits a metallic feature with weak localization. X-ray diffraction measurements have revealed that the diffraction patterns are essentially anisotropic. We have carried out the scanning of a reciprocal space in order to reveal the distribution of diffraction intensities. The result testifies to the high degree of mutual orientations of crystallites in the sample not only along the [001] direction but also in the (001) plane. Apparently the observed mosaicity of the crystal is connected with the highly anisotropic electrical properties of the rhombohedral phase of pressure-treated C[sub 60] polymer. A Dysonian ESR absorption lineshape consistent with the metallic nature was observed. [ABSTRACT FROM AUTHOR] |
