    Pressure dependence of the conduction-electron-spin-resonance linewidth of the α and β phases of di-bis(ethylenediothiolo)tetrathiafulvalene triiodide
    (1987) Forró, Laszlo; Sekretarczyk, Grazyna; Krupski, Marcin; Schweitzer, Dieter; Keller, Heimo J.
    We report conduction-electron-spin-resonance linewidth (ΔH) measurements of the α and β phases of the organic conductor di-bis(ethylenediothiolo)tetrathiafulvalene triiodide [(BEDT-TTF)2I3] in the 80–300 K temperature range under applied pressures of up to 5 kbar. ΔH increases under pressure in contrast to the predictions of the Elliot formula for the spin relaxation in metals. The pressure derivative d(lnΔH)/dP is -5.5±1%/kbar and 9.8±1%/kbar for the α and β phases of (BEDT-TTF)2I3 respectively.
