Coherent control of individual molecular spins in nanodevices is a pivotal prerequisite for fulfilling the potential promised by molecular spintronics. By applying electric field pulses during time-resolved electron spin resonance measurements, we measure the sensitivity of the spin in several antiferromagnetic molecular nanomagnets to external electric fields. We find a linear electric field dependence of the spin states in Cr7Mn, an antiferromagnetic ring with a ground-state spin of S = 1, and in a frustrated Cu-3 triangle, both with coefficients of about 2 rad s(-1)/Vm(-1). Conversely, the antiferromagnetic ring Cr7Ni, isomorphic with Cr7Mn but with S = 1/2, does not exhibit a detectable effect. We propose that the spinelectric field coupling may be used for selectively controlling individual molecules embedded in nanodevices.
