title: Weak ferromagnetism in a semiconducting (ethylenedithiodiselena- dithiafulvalenoquinone-1,3-diselenolemethide)2.FeBr4 salt.
abstract: The 2:1 salts of a new bent donor molecule, ethylenedithiodiselenadithiafulvalenoquinone-1,3-diselenolemethide (EDT-DSDTFVODS) and either an FeBr(4)- or a GaBr(4)- ion exhibit semiconducting properties and had small activation energies. The Fe(III) d spins of the FeBr(4)- salt are initially subject to a strong antiferromagnetic interaction and afterward exhibited a weak ferromagnetism at 3.8 K with a very small remanent magnetization of ca. 4 x 10(-2) mu(B) and a spin-flop near 25 kOe along the intercolumnar direction.
