    Coupling of chiralities in spin and physical spaces: The Möbius ring as a case study
    (College Park : American Physical Society, 2015) Pylypovskyi, Oleksandr V.; Kravchuk, Volodymyr P.; Sheka, Denis D.; Makarov, Denys; Schmidt, Oliver G.; Gaididei, Yuri
    We show that the interaction of the magnetic subsystem of a curved magnet with the magnet curvature results in the coupling of a topologically nontrivial magnetization pattern and topology of the object. The mechanism of this coupling is explored and illustrated by an example of a ferromagnetic Möbius ring, where a topologically induced domain wall appears as a ground state in the case of strong easy-normal anisotropy. For the Möbius geometry, the curvilinear form of the exchange interaction produces an additional effective Dzyaloshinskii-like term which leads to the coupling of the magnetochirality of the domain wall and chirality of the Möbius ring. Two types of domain walls are found, transversal and longitudinal, which are oriented across and along the Möbius ring, respectively. In both cases, the effect of magnetochirality symmetry breaking is established. The dependence of the ground state of the Möbius ring on its geometrical parameters and on the value of the easy-normal anisotropy is explored numerically.

    Printable magnetoelectronics
    (Hoboken, NJ : Wiley, 2013) Makarov, Denys; Karnaushenko, Daniil; Schmidt, Oliver G.
    The field of printable electronics is well developed. A large variety of electronic components assembled as printable optoelectronic devices and communication modules are already available. However, the element responding to a magnetic field, which is highly demanded for the concept of printable electronics has only been realized very recently. A printable magnetic sensing device has been one of the remaining missing building blocks crucial to realize the concept of entirely printable electronics. Here, we position the novel topic of printable magnetic sensorics in a family of printable electronics and highlight possible application directions of this technology.
