Quantitative atomic order characterization of a Mn2FeAl Heusler epitaxial thin film
Abstract
In this work, we investigate the effect of anti-site disorder on the half-metallic properties of a Mn2 FeAl Heusler alloy thin film. The film was grown...

Quantum analysis of second-order effects in superconducting travelling-wave parametric amplifiers
Abstract: We have performed a quantum mechanical analysis of travelling-wave parametric amplifiers (TWPAs) in order to investigate five experimental phenomena related to their operations, namely the effect of impedance mismatch...
