ac Calorimetry and EPR Study on Metal-Insulator Transition and Glass Transition in an Organic Conductor with Double-Column Structure, (DIMET)_2BF_4 : Condensed Matter: Electronic Properties, etc.

概要
- 論文の詳細を見る
Successive metal-insulator transitions in (DIMET)_2BF_4 were studied by chopped-light ac calorimetry and electron paramagnetic resonance (EPR) measurement. An anomaly due to the metal-insulator transitions has been clearly detected in ac calorimetry between 20 and 35K. In contrast to other double-column salts (DMET)_2BF_4 and (DMET)_2CIO_4, successive metal-insulator transitions detected in transport properties are shown to be thermodynamic phase transitions. The EPR detected an anomaly only for the lowest transition around 12K. The properties of the metal-insulator transitions are compared among the DIMET and DMET salts having the double-column structure. A frequency-dependent step in heat capacity was detected around 110 K. The step-like anomaly is attributed to a glass transition due to freezing of the intramolecular motion of the ethylene group in the ET moiety within a DIMET molecule.
