Properties of Organic Superconductors.
Abstract
The major results were: 1. Discovery of a new class of organic superconductors based on the (BEDT-TTF) molecule. This discovery has proven to be very important since recent chemical modification of our (BEDT-TTF) compound has led to a superconducting transition temperature of 8K, quite high for an organic solid. This offers the possibility that superconductivity can be found at temperatures greater than inorganic materials. The characterization of the (BEDT-TTF)2X superconductors included transport, magnetic and structural properties and these are discussed in the reference. 2. Measurement of the far IR properties of (TMTSF)2 C1O4. These results proved that a large superconductivity gap does not exist in (TMTSF)2 C1O4, contrary to previous speculations and erroneous interpretation of data by other workers. This rules out the possibility of superconducting fluctuations in the (TMTSF)2X class of organic superconductors. 3. Observation of now features of the magnetic-field-induced transition in (TMTSF)2 C1O4. The field-induced-transition (FIT) is quite anomalous and appears to be unique in solid state physics. The Hall effect and the magnetoresistance of (TMTSF)2 C1O4 was measured as a function of magnetic field up to 20T.
