Query: Piezo-Magnetoelectric Effect of Spin Origin in Dysprosium Orthoferrite   Piezo-magnetoelectric effect, namely simultaneous induction of both the
ferromagnetic moment and electric polarization by an application of uniaxial
stress, was achieved in the non-ferroelectric and antiferromagnetic ground
state of DyFeO$_3$. The induced electric polarization and ferromagnetic moment
are coupled with each other, and monotonically increase with increasing
uniaxial stress. The present work provides a new way to design spin-driven
multiferroic states, that is, magnetic symmetry breaking forced by external
uniaxial stress.
