Journal ArticleDOI
Fine structure in magnetization of individual fluxoid states
Andre K. Geim,S. V. Dubonos,Juan Jose Palacios,Irina V. Grigorieva,Mohamed Henini,J. J. Schermer +5 more
TL;DR: This work finds clear signatures of first and second order transitions within the states of fluxoid states, which reveal the existence of distinct vortex phases for a fixed number of fluxoids.
Journal ArticleDOI
Memory effects in individual submicrometer ferromagnets
TL;DR: In this paper, the magnetization of individual submicrometer nickel disks (80 nm high, $0.1--1.0\ensuremath{\mu}\mathrm{m}$ diameter) was studied and it was shown that hysteresis loops of the disks no longer show inversion symmetry in a magnetic field.
Journal ArticleDOI
Submicron probes for Hall magnetometry over the extended temperature range from helium to room temperature
Kostya S. Novoselov,Sergey V. Morozov,S. V. Dubonos,Mohamed Missous,A. O. Volkov,D. A. Christian,Andre K. Geim +6 more
TL;DR: In this paper, mesoscopic Hall sensors made from various materials and their suitability for accurate magnetization studies of submicron samples over a wide temperature range and, especially, at room temperature.
Journal ArticleDOI
Scattering of ballistic electrons at a mesoscopic spot of strong magnetic field
Kostya S. Novoselov,Andre K. Geim,S. V. Dubonos,Y.G. Cornelissens,François M. Peeters,Jan C. Maan +5 more
TL;DR: In this article, the authors report quenching of the Hall effect with increasing magnetic field confined in a micron-sized spot, which is explained by a rapid increase in the number of electrons that are scattered or quasilocalized by the magnetic region.
Journal ArticleDOI
Vortex states in mesoscopic superconducting squares: Formation of vortex shells
H. J. Zhao,Vyacheslav R. Misko,François M. Peeters,V. A. Oboznov,S. V. Dubonos,Irina V. Grigorieva +5 more
TL;DR: In this paper, the first direct visualization of vortex patterns in micrometer-sized Nb squares, using the Bitter decoration technique, was presented, although in a different manner than in disks, in terms of formation of vortex ''shells''.
