RInO3 (R: rare-earth element) has attracted unprecedented research attention due to its geometric ferroelectricity and spin liquid state. However, further investigation on the structure-property relationship based on well-developed single crystals is needed. A EuInO3 crystal was obtained for the first time by the laser floating zone method. The presence of ferroelectricity and interesting topological vortex domains were revealed, providing great potential for vortex memory devices.
RInO3 (R: rare-earth element) has drawn unprece-dented research attention due to its geometric ferroelectricity and spin liquid state. However, the structure-property relationship needs further investigation based on well-developed single crystals. A EuInO3 crystal was obtained for the first time by the laser floating zone method. The presence of ferroelectricity was revealed by polarization-electric field hysteresis loops of the bulk EuInO3 single crystal. Moreover, interesting topological vortex domains were revealed by vertical piezoresponse force microscopy. The lattice dynamics of EuInO3 was probed by correlating various Raman modes with the structural distortion of the unit cell. The improper ferroelectricity and topological ferroelectric vortices of the EuInO3 crystal provide great potential for vortex memory devices.
