Foury-Leylekian It is established that the multiferroics RMn 2 O 5 crystallize in the centrosymmetric Pbam space group and that the magnetically induced electric polarization appearing at low temperature is accompanied by a symmetry breaking. However, both our present x-ray study—performed on compounds with R=Pr,Nd,Gd... [Phys. Rev. Lett. 114, 117601] Published Mon Mar 16, 2015
