Magnetic, dielectric and magnetoelectric properties of new family of orthorhombic multiferroic Eu1− x Y x MNO3 manganites

Abstract: Multiferroic ground states with a spatially modulated antiferromagnetic structure and electric polarization have been revealed in Eu1− x Y x MnO3 () single crystals. While the slightly substituted () compounds exhibited a transition from the incommensurate (IC) to the canted antiferromagnetic (CAF) state at , the transitions from IC to commensurate ferroelectric (C/FE) phase were observed at for . Various phase transitions were observed in the magnetic fields up to 250kOe along a, b, c axes by magnetization, magnetostriction and electric polarization measurements which show an existence of a spontaneous electric polarization below T lock.
