Magnetocaloric effect (MCE) and magnetic torque measurements have been carried out in the π–d system λ-(BETS)2FeCl4 [BETS = bis(ethylenedithio)tetraselenafulvalene], which shows an antiferromagnetic insulating (AFI) phase below ∼8.5 K. In the magn...

Systematic measurements of the magnetic torque tau of the organic conductor lambda-(BETS)(2)FeCl4 have been performed to investigate the magnetic properties. In the magnetic field dependence of t, a very sharp structure is observed at similar to 1...
A quantum spin-liquid state, an exotic state of matter, appears when strong quantum fluctuations enhanced by competing exchange interactions suppress a magnetically ordered state. Generally, when an ordered state is continuously suppressed to 0 K ...
