Defect engineering is one of the cornerstones of the modern electronics industry. Almost all electronic devices include materials that have been doped by ion bombardment. For materials where crystallinity is essential, such as ferroelectrics, defect type a ...
The growing library of two-dimensional layered materials is providing researchers with a wealth of opportunity to explore and tune physical phenomena at the nanoscale. Here, we review the experimental and theoretical state-of-art concerning the electron sp ...
Here we show that it is possible to produce different magnetic core multiple shell heterostructures from monodisperse Fe3O4 spherical magnetic seeds by finely controlling the amount of a manganese precursor and using, in a smart and simple way, a cation-ex ...
Recent developments in the physics of non-magnetic ferroics identified possible functionality of domain walls in these materials, which specifies the current interest to the internal structure of the walls. In this context, the wall thickness itself can be ...
In contrast to the flexible rotation of magnetization direction in ferromagnets, the spontaneous polarization in ferroelectric materials is highly confined along the symmetry-allowed directions. Accordingly, chirality at ferroelectric domain walls was trea ...
The motion of ferroelectric domain walls greatly contributes to the macroscopic dielectric and piezoelectric response of ferroelectric materials. The domain-wall motion through the ferroelectric material is, however, hindered by pinning on crystal defects, ...
The 1/4-filled organic compound, delta-(EDT-TTF-CONMe2)(2)AsF6 is a frustrated two-dimensional triangular magnetic system as shown by high-frequency (111.2 and 222.4 GHz) electron spin resonance (ESR) and structural data in the literature. The material gra ...
High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0
Sr2CuWO6 is a double perovskite proposed to be at the border between two- and three-dimensional magnetism, with a square lattice of S = 1/2 Cu2+ ions. We have used inelastic neutron scattering to investigate the spin wave excitations of the system, to find ...
Neutron scattering from single crystals has been used to determine the magnetic structure and magnon dynamics of FePS3, an S = 2 Ising-like quasi-two-dimensional antiferromagnet with a honeycomb lattice. The magnetic structure has been confirmed to have a ...
The high Curie temperature (T-C similar to 825 degrees C) of BiFeO3 has made this material potentially attractive for the development of high-T-C piezoelectric ceramics. Despite significant advances in the search of new BiFeO3-based compositions, the piezo ...
