Detailed magnetization measurements enabled us to claim that the layered organic insulator κ-(BEDT-TTF)2Cu[N(CN)2]Cl [BEDT-TTF: bis(ethylenedithio)tetrathiafulvalene] with Dzyaloshinskii–Moriya interaction has an antiferromagnetic spin structure easy axis being crystallographic c-axis and net canting moment parallel a-axis at zero magnetic field. This zero-field is significantly different from proposed in past studies. The assignment was achieved by arguments including a correction of...
We attempted to assign the spin structure of a layered organic antiferromagnet, $\ensuremath{\kappa}$-(d8-BEDT-${\mathrm{TTF})}_{2}\mathrm{Cu}[\mathrm{N}{(\mathrm{CN})}_{2}]\mathrm{Br}$, which is key material located closest Mott boundary at ambient pressure among this family compounds, by investigating its macroscopic magnetization thoroughly, motivated recent successful assignment an isostructural material,...
The band structure and magnetic properties of organic charge-transfer salt $\ensuremath{\lambda}\text{\ensuremath{-}}{(\text{BEDSe-TTF})}_{2}{\mathrm{GaCl}}_{4}$ [BEDSe-TTF: bis(ethylenediseleno)tetrathiafulvalene; abbreviated as $\ensuremath{\lambda}$-BEDSe] are investigated. reported crystal is confirmed using x-ray diffraction measurements, the transfer integrals calculated. degree electron correlation $U/W$ ($U$: on-site Coulomb repulsion, $W$: bandwidth) $\ensuremath{\lambda}$-BEDSe...
