Anomalous Hall effect in a two dimensional electron gas with magnetic impurities
Tamara S. Nunner, Gergely Zarand, Felix von Oppen
Magnetic impurities play an important role in many spintronics-related materials. Motivated by this fact, we study the anomalous Hall effect in the presence of magnetic impurities,…
Scaling analysis of the magnetoresistance in Ga_{1-x}Mn_xAs
C. P. Moca, B. L. Sheu, N. Samarth +3
We compare experimental resistivity data on Ga_{1-x}Mn_xAs films with theoretical calculations using a scaling theory for strongly disordered ferromagnets. All characteristic featu…
Theory of Manganese-Manganese interaction in GaMnAs
P. Redlinski, G. Zarand, B. Janko
We investigate the interaction of two Mn ions in the dilute magnetic semiconductor GaMnAs using the variational envelope wave function approach within the framework of six band mod…
Disorder, spin-orbit, and interaction effects in dilute
Gregory A. Fiete, Gergely Zarand, Kedar Damle +1
We derive an effective Hamiltonian for in the dilute limit, where can be described in terms of spin …
Scaling theory of magneto-resistance in disordered local moment ferromagnets
Gergely Zarand, Catalin Pascu Moca, Boldizsar Janko
We present a scaling theory of magneto-transport in Anderson-localized disordered ferromagnets. Within our framework a pronounced magnetic-field-sensitive resistance peak emerges n…
Positional Disorder, Spin-Orbit Coupling and Frustration in GaMnAs
Gregory A. Fiete, Gergely Zarand, Boldizsar Janko +2
We study the magnetic properties of metallic GaMnAs. We calculate the effective RKKY interaction between Mn spins using several realistic models for the valence band structure of G…
