The first semiquinone-bridged bisdithiazolyl radical conductor: a canted antiferromagnet displaying a spin-flop transition

摘要

The alternating ABABAB it-stacked bis-1,2,3-dithiazolyl radical 2a (2, R_2 = Ph) has a conductivity σ of 3 × 10~(-5) S cm~(-1) at 300 K, and orders as a spin-canted antiferromagnet ( T_n = 4.5 K) which undergoes a spin-flop transition to a field-induced ferromagnetic state saturating (at 2 K) at H ~ 20 kOe.
