Observation of unconventional van der Waals multiferroics near room temperature
arxiv(2023)
Abstract
The search for two-dimensional (2D) van der Waals (vdW) multiferroics is an
exciting yet challenging endeavor. Room-temperature 2D vdW few-layer
multiferroic is a much bigger insurmountable obstacle. Here we report the
discovery of an unconventional 2D vdW multiferroic with out-of-plane
ferroelectric polarization and long-range magnetic orders in trilayer NiI2
device from 10 K to 295 K. The evolutions of magnetic domains with magnetic
field, and the evolutions between ferroelectric and antiferroelectric phase
have been unambiguously observed. More significantly, we realize a robust
mutual control of magnetism and ferroelectricity at room temperature. The
magnetic domains are manipulated by a small voltage ranging from 1 V to 6 V at
0 T and 295 K. This work opens opportunities for exploring multiferroic physics
at the limit of few atomic layers.
