Superconductors (S) can be employed to probe the spin polarization of ferromagnetic metals (F) by virtue of Andreev reflection. Using nanocontacts defined by e-beam lithography, the spin-polarization of the current across an S/F interface can be dete

In Nb/Ag layers, the induced superconductivity in Ag by Nb gives rise to diamagnetic screening currents in the Ag layer well below the transition temperature of the superconductor. By investigating the position dependence of the individual diamagneti

The magnetic flux generated by the screening currents of a superconducting Nb film in the Meissner state is measured with a coaxial gradiometer in a weak magnetic field B. A peculiar position dependence is found when the sample surface is only slight

A comprehensive investigation is presented of E- and H-plane scan-frequency characteristics of probe-fed microstrip strip-element phased arrays with a single probe per unit cell. A parametric study of the principal, large mismatch producing scan reso

Our previous point-contact Andreev reflection studies of the heavy-fermion superconductor CeCoIn$_5$ using Au tips have shown two clear features: reduced Andreev signal and asymmetric background conductance [1]. To explore their physical origins, we

In superconducting Nb/Ag double layers, a diamagnetic transition occurs in the magnetization at a temperature T b below the transition temperature of Nb due to the proximity-induced superconductivity (PIS) in Ag. For triple layers, where Ag is squeez
