| الوصف: | According to previous theoretical work, the binary oxide CuO can become a room-temperature multiferroic via tuning of the superexchange interactions by application of pressure. Thus far, however, there has been no experimental evidence for the predicted room-temperature multiferroicity. Here, we show by neutron diffraction that the multiferroic phase in CuO reaches 295 K with the application of 18.5 GPa pressure. We also develop a spin Hamiltonian based on density functional theory and employing superexchange theory for the magnetic interactions, which can reproduce the experimental results. The present Letter provides a stimulus to develop room-temperature multiferroic materials by alternative methods based on existing low temperature compounds, such as epitaxial strain, for tunable multifunctional devices and memory applications. © 2022 American Physical Society. ; Engineering and Physical Sciences Research Council, EPSRC ; Japan Society for the Promotion of Science, KAKEN, (15H05433, 17KK0099, 22H00297) ; Horizon 2020, (645660) ; JST-Mirai Program, (AAAA-A18-118020190095-4, JPMJMI18A3) ; We would like to thank Takayuki Harada of the National Institute for Materials Science for fruitful discussion, and Jérôme Debray and Claire V.
