Abstract

A new bromo-bridged NiIII compound has been synthesized. This compound displayed a strong antiferromagnetic interaction between spins located on NiIII species (J = (2350 ± 500) K) that result from the strong covalency of the Ni - Br bond and the spin-Peierls transition below 150K. This was shown by the results of magnetic susceptibility and 81Br nuclear quadrupole resonance spectroscopy analysis. We succeeded in the electrostatic carrier doping of a single crystalline sample by using a field-effect transistor device. This compound also showed n-type semiconductor behavior, which can be reasonably rationalized by the existence of a small amount of NiII impurities.
