New article in JACS

Following our previous work demonstrating the magnetoelectric coupling of spin triangles in static electric fields, our most recent publication in JACS shows how we can use pulsed electric fields to achieve the coherent manipulation of spin triangles. In this work we show that the magnetoelectric coupling is highly anisotropic with respect to the molecular orientation inside the magnetic and electric fields. By comparing the behaviour of the ferric triangle [Fe₃O(O₂CPh)₆(py)₃]ClO₄·py and the chromic triangle [Cr₃O(O₂CPh)₆(py)₃]ClO₄·0.5py, and by using Katsura's model for the spin-induced electri cpolarization, we propose the magnetic properties that are more likely to give rise to magnetoelectric coupling.
