The intrinsic magnetic structure and ordering of multiferoic h-LuFeO$_{3}$ Films
ORAL
Abstract
It has been previously reported that h-LuFeO$_{3}$ films are ferroelectric and magnetically ordered above room temperature [1]. During this talk, we discuss our recent results [2] on well characterized molecular beam epitaxy grown films. While we find the films are ferroelectric at room temperature, we find that films grown on both YSZ (111) and Al$_{2}$O$_{3}$ (0001) substrates are magnetically ordered well below room temperature. The magnetic order is the standard 120 degree structure found in these materials, with a canted moment out of the a-b plane. We find that the magnetic structure of these films is consistent with the possibility of switching this small canted moment with an electric field [3]. \\[4pt] [1] W. Wang et al, Phys. Rev.
