Large Magnetoresistance Induced by Quantum Charge Fluctuations in Magnetic Double Dots
L. Sheng, D. Y. Xing, D. N. Sheng
We study electron tunneling through two small ferromagnetic dots. Quantum charge fluctuations and interdot coupling make each Coulomb peak of the conductance at zero interdot coupl…

Spin injection efficiency from two adjoining ferromagnetic metals into a two-dimensional electron gas
Jun Wang, D. Y. Xing, H. B. Sun
In order to enhance spin injection efficiency from ferromagnetic (FM) metal into a two-dimensional electron gas (2DEG), we introduce another FM metal and two tunnel barriers (I) be…

Quantum interference effect on the density of states in disordered d-wave superconductors
Y. H. Yang, Y. G. Wang, M. Liu +1
The quantum interference effect on the quasiparticle density of states (DOS) is studied with the diagrammatic technique in two-dimensional d-wave superconductors with dilute nonmag…
