Quantum coherent spin–electric control in a molecular nanomagnet at clock transitions

Electrical control of spins at the nanoscale offers significant architectural advantages in spintronics, because electric fields can be confined over shorter length scales than magnetic fields. Thus, recent demonstrations electric-field (E-field) sensitivities molecular spin materials are tantalising, raising viability quantum analogues macroscopic magneto-electric devices.However, E-field reported so far rather weak, prompting question how to design molecules with stronger spin-electric couplings. Here we show that one path is identify an energy scale spectrum associated a structural degree freedom electrical polarisability. We study example nanomagnet which small distortion establishes clock transitions (i.e. whose first order independent field) spectrum; fact this dipole allows us transition unprecedented degree. demonstrate coherent state and exploit it manipulate independently two magnetically-identical but inversion-related unit cell crystal. Our findings pave way for use technologies spintronics.
