      Engineered Magnetization and Exchange Stiffness in Direct-Write Co-Fe Nanoelements 

      Bunyaev, S. A.; Budinska, B.; Sachser, Roland; Wang, Q.; Levchenko, K.; Knauer, S.; Bondarenko, A. V.; Urbanek, M.; Gusliyenko, Kostyantyn; Chumak, Andrii V.; Huth, Michael; Kakazei, Gleb N.; Dobrovolskiy, O. V. (American Institute of Physics, 2021-01-11)
      Media with engineered magnetization are essential building blocks in magnonics, spintronics, and superconductivity. However, the established thin film and lithographic techniques insufficiently suit the realization of ...

      Higher order vortex gyrotropic modes in circular ferromagnetic nanodots 

      Ding, Junjia; Kakazei, Gleb N.; Liu, Xinming; Gusliyenko, Kostyantyn; Adeyeye, Adekunle O. (Nature Publishing Group, 2014-04-25)
      Magnetic vortex that consists of an in-plane curling magnetization configuration and a needle-like core region with out-of-plane magnetization is known to be the ground state of geometrically confined submicron soft magnetic ...

      How dry is dry? Molecular mobility in relation to thallus water content in a lichen 

      Dobrovolskiy, Oleksandr V.; Bunyaev, Sergey A.; Vovk, Nikolay R.; Navas, David; Gruszecki, Pawel; Krawczyk, Maciej; Sachser, Roland; Huth, Michael; Chumak, Andrii V.; Gusliyenko, Kostyantyn; Kakazei, Gleb N. (Royal Society Of Chemistry, 2020-11-07)
      The increasing demand for nanoscale magnetic devices requires development of 3D magnetic nanostructures. In this regard, focused electron beam induced deposition (FEBID) is a technique of choice for direct-writing of complex ...

      Magnetic properties of permalloy antidot arrayfabricated by interference lithography 

      Silva, A. S.; Hierro Rodríguez, A.; Bunyaev, S. A.; Kakazei, Gleb N.; Dobrovolskiy, O. V.; Redondo Esteban, Carolina ORCID; Morales Arboleya, Rafael ORCID; Crespo, H.; Navas Otero, David (American Institute of Physics, 2019-03)
      The interference laser lithography and ion-beam sputtering have been reported. Magneto-optical Kerr effect magnetometry indicated that the sample exhibits four-fold anisotropic behaviour, i.e. different magnetization loops ...

      Microwave absorption properties of permalloy nanodots in the vortex and quasi-uniform magnetization states 

      Gusliyenko, Kostyantyn; Kakazei, Gleb N.; Kobljanskyj, Yu V.; Melkov, G. A.; Novosad, V.; Slavin, A. N. (IOP Publishing, 2014-06-19)
      When the in-plane bias magnetic field acting on a flat circular magnetic dot is smaller than the saturation field, there are two stable competing magnetization configurations of the dot: the vortex and the quasi-uniform ...

      Route to form skyrmions in soft magnetic films 

      Navas Otero, David; Verba, R. V.; Hierro Rodríguez, A.; Bunyaev, S. A.; Zhou, X.; Adeyeye, Adekunle O.; Dobrovolskiy, O. V.; Ivanov, B. A.; Gusliyenko, Kostyantyn; Kakazei, Gleb N. (American Institute of Physics, 2019-08)
      Magnetic skyrmions which are topologically nontrivial magnetization configurations have attracted much attention recently due to their potential applications in information recording and signal processing. Conventionally, ...
