Phase-Controlled Force and Magnetization Oscillations in Superconducting Ballistic Nanowires
arXiv:cond-mat/0402106 · doi:10.1103/PhysRevLett.92.126802
Abstract
The emergence of superconductivity-induced phase-controlled forces in the (0.01-0.1) nN range, and of magnetization oscillations, in nanowire junctions, is discussed. A giant magnetic response to applied weak magnetic fields, is predicted in the ballistic Josephson junction formed by a superconducting tip and a surface, bridged by a normal metal nanowire where Andreev states form.
