Domain Wall Assisted Magnetic Recording
A. Yu. Dobin, H. J. Richter
Using numerical and analytical micromagnetics we calculated the switching fields and energy barriers of the composite (exchange spring) magnetic recording media, which consist of l…
Exchange Field Induced Magnetoresistance in Colossal Magnetoresistance Manganites
I. N. Krivorotov, K. R. Nikolaev, A. Yu. Dobin +2
The effect of an exchange field on electrical transport in thin films of metallic ferromagnetic manganites has been investigated. The exchange field was induced both by direct exch…
Magnetostructural effects and phase transition in Cr_2O_3 under pressure
Alexander Yu. Dobin, Wenhui Duan, Renata M. Wentzcovitch
We have successfully calculated the electronic and structural properties of chromia (Cr_2O_3) in the Local Spin Density Approximation (LSDA). We predict a transformation from the c…
Oscillatory Exchange Coupling and Positive Magnetoresistance in Epitaxial Oxide Heterostructures
K. R. Nikolaev, A. Yu. Dobin, I. N. Krivorotov +7
Oscillations in the exchange coupling between ferromagnetic layers with paramagnetic spacer layer thickness has been observed in epitaxial heteros…
Localization length at the resistivity minima of the quantum Hall effect
M. M. Fogler, A. Yu. Dobin, B. I. Shklovskii
The resistivity minima of the quantum Hall effect arise due to the localization of the electron states at the Fermi energy, when it is positioned between adjacent Landau levels. In…
Suppression of chaotic dynamics and localization of two-dimensional electrons by a weak magnetic field
M. M. Fogler, A. Yu. Dobin, V. I. Perel +1
We study a two-dimensional motion of a charged particle in a weak random potential and a perpendicular magnetic field. The correlation length of the potential is assumed to be much…
