Chemical control of a molecular spin switch in the presence of a gate

Abstract

We predict that the electric field induced spin-crossover in a double –NO₂ substituted Fe(II) complex will commence at the gate voltage, V_G = −1.04 V and across this critical V_G, the low and high spin states behave as “off” and “on” state, respectively which paves a unique way to realize an electronic spin switch controlled by a gate.
