Electron-electron correlations with particular attention to m-BDNT-PF6: spin susceptibility

The new BDNT-PF6 (m-BDNT-PF6) (BDNT = 4,9-bis (1,3-benzodithiol-2-ylidine)-4,9dihydronaphth [2,c] [1,2,5] thiadiazole) salt is classified as a half -filled correlated electron system. The calculated temperature dependence of spin susceptibility is in agreement with the visualized BDNT-PF6 magnetization from SQUID and ESR measurements.
