abstract = {Here we report on P−E hysteresis loop measurements that
unravel the ferroelectric nature of melanothallite Cu2OCl2,
a new multiferroic material with high critical temperature.
Its spin structure was investigated by polarized and
unpolarized neutron scattering experiments which reveal a
cycloidal magnetic structure with vector chirality (magnetic
polarity) that can be inverted by opposite poling of the
sample with an inverted electric field. This shows that
Cu2OCl2 is a spin-induced ferroelectric material. Finally,
we show that the ferroelectric properties of Cu2OCl2 are
driven by the inverse Dzyaloshinskii-Moriya interaction
mechanism which is also able to predict the observed
direction of the ferroelectric polarization properly. The
origin of the noncollinear spin structure in melanothallite
are competing AFM-FM exchange couplings which we estimate
from a combined ab initio + cluster configuration
interaction calculation.},
