Kondo effect in quantum dots coupled to ferromagnetic leads
J. Martinek, Y. Utsumi, H. Imamura +4
We study the Kondo effect in a quantum dot which is coupled to ferromagnetic leads and analyse its properties as a function of the spin polarization of the leads. Based on a scalin…
Nonequilibrium spin fluctuations in single-electron transistors
Jan Martinek, Józef Barnas, Gerd Schön +2
We show that nonequilibrium spin fluctuations significantly influence the electronic transport in a single-electron transistor, when the spin relaxation on the island is slow compa…
Spin accumulation in ferromagnetic single-electron transistors in the cotunneling regime
Jan Martinek, Józef Barnas, Sadamichi Maekawa +2
We propose a new method of direct detection of spin accumulation, which overcomes problems of previous measurement schemes. A spin dependent current in a single-electron transistor…
A new mechanism of exchange interaction in ferromagnetic semiconductors
V. K. Dugaev, V. I. Litvinov, J. Barnas +1
We propose a new mechanism of indirect exchange interaction, which can be responsible for the ferromagnetic ordering in Mn-doped semiconductors (like GaMnAs) at low carrier concent…
