Abstract:
Motivated by the recent theoretical discussions on the
implications of x-ray resonant scattering and linear dichroism
data, we have measured the magnetoelectric effect in V2O3. We
were not able to detect any effect and could fix an upper limit
for the magnetoelectric susceptibility alphaless than or equal
to0.01 ps/m. Moreover, we could verify that it is impossible to
perform a magnetoelectric annealing on the system at the
transition temperature, because of its small electrical
resisitivity. This finding has precise implications on the
ground-state properties of the system.
