Spectroscopy of phonons and spin torques in magnetic point contacts
I. K. Yanson, Yu. G. Naidyuk, D. L. Bashlakov +4
Phonon spectroscopy is used to investigate the mechanism of current-induced spin torques in nonmagnetic/ferromagnetic (N/F) point contacts. Magnetization excitations observed in th…
Giant oscillations of the density of states and the conductance in a ferromagnetic conductor coupled to two superconductors
A. Kadigrobov, R. I. Shekhter, M. Jonson
Giant oscillations of the density of electronic states and the differential conductance of a superconductor-ferromagnet-superconductor structure are predicted for the case when the…
Single-interface superconductivity in two-layer semiconductor heterostructures
N. Ya. Fogel, E. I. Buchstab, Yu. V. Bomze +6
We have discovered superconductivity in the two-layer semiconducting monochalcogenide heterostrutures PbTe/PbS, PbTe/PbSe and PbTe/YbS. By comparing data from two-layer samples wit…
Microwave controlled phase coherent transport in mesoscopic S-N-S structures
N. I. Lundin, L. Y. Gorelik, R. I. Shekhter +2
We show that transport through a superconducting quantum point contact biased at subgap voltages is strongly affected by a microwave field. The subgap current is increased by sever…
Giant conductance oscillations in a normal mesoscopic ring induced by an SNS Josephson current
A. Kadigrobov, A. Zagoskin, R. I. Shekhter +1
A theoretical explanation of giant conductance oscillations observed in normal mesoscopic rings with superconducting ``mirrors" is proposed. The effect is due to resonant tuning of…
Soft Disorder Effects in the Conductance Quantization in Quantum Point Contacts: Indirect Backscattering Statistics
A. M. Zagoskin, S. N. Rashkeev, R. I. Shekhter +1
The breakdown of conductance quantization in a quantum point contact in the presence of random long-range impurity potential is discussed. It is shown that in the linear response r…
