Abstract
Y-type hexaferrites are one of the most promising multiferroic materials for applications that allow electric field control of magnetization near room temperature. Here, the authors systematically investigate the stability of competing magnetic and multiferroic phases for several Y-type hexaferrite single crystals by performing magnetization, polarization, and neutron diffraction measurements. They also study the magnetization-polarization coupling by simultaneously applying electric and magnetic fields, and reveal how it changes as a function of temperature.
