Magnetism of oxide antiferromagnets (AFMs) has been studied in single crystals and extended thin films. The properties of AFM nanostructures still remain underexplored. Here, we report on the fabrication and magnetic imaging of granular 100 nm-thick magnetoelectric Cr2O3 films patterned in circular bits with diameters ranging from 500 down to 100…
Curvilinear magnetism of nanostripes is a prospective playground both for fundamental research and numerous applications. By tailoring geometrical properties of the ferromagnetic stripes and wires there appear new possibilities to control its magnetic properties such as the dynamics of the domain walls. Deterministic fast motion of the domain walls is…
A search for high-speed and low-energy memory devices puts antiferromagnetic thin films at the forefront of spintronic research. Here, we develop a material model of a granular antiferromagnetic thin film with uniaxial anisotropy and provide fundamental insight into the interaction of antiferromagnetic domain walls with grain boundaries. This model is…
Curved magnetic architectures are key enablers of prospective magnetic devices with respect to size, functionality, and speed. By exploring geometry-governed magnetic interactions, curvilinear magnetism offers a number of intriguing effects in curved magnetic wires and curved magnetic films. The applicability of the current micromagnetic theory requires that the sample has…
Chiral effects originate from the lack of inversion symmetry within the lattice unit cell or sample’s shape. Being mapped onto magnetic ordering, chirality enables topologically non-trivial textures with a given handedness. Here, we demonstrate the existence of a static 3D texture characterized by two magnetochiral parameters being magnetic helicity of…

30 жовтня пішов з життя видатний фізик-теоретик, доктор фіз.-мат. наук, професор Юрій Борисович Гайдідей Колектив Інституту теоретичної фізики ім. М.М. Боголюбова НАН України, колектив групи RiTM глибоко сумують з приводу непоправної втрати і висловлюють щирі співчуття рідним і близьким покійного. Кремація відбудеться на Байковому цвинтарі 1 листопада о 12 годині…
One extremely snowy day, part of RiTM group met in Helmholtz-Zentrum Dresden Rossendorf. Potentially new member tries to tunnel through metal wall behind us.
Last time we wrote how to use Git + TeXStudio (especially with Overleaf) bundle to collaborate on papers and track changes. During the work it may be useful to show information about current commit/author/(time of change) directly in the document. We found a few ways to do it. The simplest…
