Single channel conductance of H molecules attached to platinum or palladium electrodes
V. M. Garcia-Suarez, A. R. Rocha, S. W. Bailey +3
We report a detailed theoretical study of the bonding and conduction properties of an hydrogen molecule joining either platinum or palladium electrodes. We show that an atomic arra…
Different origin of the ferromagnetic order in (Ga,Mn)As and (Ga,Mn)N
Malgorzata Wierzbowska, Daniel Sanchez-Portal, Stefano Sanvito
The mechanism for the ferromagnetic order of (Ga,Mn)As and (Ga,Mn)N is extensively studied over a vast range of Mn concentrations. We calculate the electronic structures of these m…
Asymmetric I-V characteristics and magnetoresistance in magnetic point contacts
A. R. Rocha, S. Sanvito
We present a theoretical study of the transport properties of magnetic point contacts under bias. Our calculations are based on the Keldish's non-equilibrium Green's function forma…
