      Magnetic properties of permalloy antidot arrayfabricated by interference lithography 

      Silva, A. S.; Hierro Rodríguez, A.; Bunyaev, S. A.; Kakazei, G. N.; Dobrovolskiy, O. V.; Redondo Esteban, Carolina; Morales Arboleya, Rafael; 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, G. 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 ...
