Cupric oxide single crystal thin films were grown by plasma-assisted molecular beam epitaxy. X-ray diffraction, Raman spectrum and in situ reflection high-energy electron diffraction show that the thin films are 2x2 reconstructed with an in-plane compression and out-of-plane stretching. Thermal stimulated current measurement indicates that the electric polarization response presents in the special 2D cupric oxide single crystal thin film over a wide temperature range from 130 K to near-room…

Epitaxial BiFeO3 Multiferroic Thin Film Heterostructures
Enhanced polarization and related properties in heteroepitaxially constrained thin films of the ferroelectromagnet, BiFeO3, and combined functional responses in thin film form present an opportunity to create and implement thin film devices that actively couple the magnetic and ferroelectric order parameters.
A New Approach to Single Crystal Growth of CuO
The study of the mechanism of superconductivity in high-T{sub c} copper oxide superconductors requires knowledge of their simplest mother material, CuO. The authors present a novel method for
Room-temperature spin-spiral multiferroicity in high-pressure cupric oxide
It is established that pressure-driven phase competition induces a giant stabilization of the multiferroic phase of CuO, which at 20-40 GPa becomes stable in a domain larger than 300 K, from 0 to T > 300 K.
Raman scattering from cupric oxide
Abstract Raman scattering experiments have been carried out on Cupric Oxide (CuO) throughout the temperature range from 15K to 300K. The three Raman active modes predicted by group theory have been
Short-range magnetic order and temperature-dependent properties of cupric oxide.
This work shows that the spin exchange interactions in CuO are neither fully one-dimensional nor fully three-dimensional.
Magnetic neutron scattering study of single-crystal cupric oxide.
Among Cu/sup 2+/ compounds, cupric oxide (CuO) has unusual magnetic properties, some of which are shared by the superconducting copper oxides, and neutron scattering experiments on a CuO single crystal have been performed to study these properties.
High pressure neutron diffraction investigation of CuO
The dependence of the magnetic structure of CuO on hydrostatic pressure up to 18 kbar has been studied by means of neutron diffraction at low temperatures. The pressure dependences of both the Neel
Magnetism in cupric oxide
Single-crystal neutron diffraction measurements have been used to study the long-range magnetic ordering in cupric oxide, CuO. An incommensurate antiferromagnetic structure forms below the Neel
High-T(c) ferroelectricity emerging from magnetic degeneracy in cupric oxide.
Cupric oxide is multiferroic at unusually high temperatures. From density functional calculations we find that the low-T magnetic phase is paraelectric, and the higher-T one is ferroelectric with a
