Journal ArticleDOI
Electrical-transport, magneto-transport and magnetic anisotropy of epitaxially grown MnAs/GaAs hybrid multilayers
TL;DR: In this article, the authors successfully fabricated epitaxial MnAs/GaAs multilayers with a total thickness of 300 nm using molecular beam epitaxy, and the periodicity of the samples was varied from 0.5 to 10 nm.
Journal ArticleDOI
Anisotropic Ultrasound Propagation in a Cholesteric Liquid Crystal
TL;DR: In this paper, a detailed study of the propagation of longitudinal ultrasound through a magnetically aligned cholesteric liquid crystal (a mixture of cholesteryl chloride and Cholesteryl myristate, 1.75: 1 by weight) is reported.
Journal ArticleDOI

TL;DR: In this article, the chemical and structural properties of epitaxial Y 1 Ba 2 Cu 3 (F)O thin films, fabricated by multilayer electron beam evaporation, are evaluated, both laterally and vertically, as a function of various annealing schedules by secondary ion mass spectrometry (SIMS) using a high resolution scanning ion microprobe.
Journal ArticleDOI
Stimulated emission of free excitons in Cd1-xMnxTe under nonresonant two photon excitation
TL;DR: In this paper, free excitons coexisting with exciton magnetic polarons (EMPs) in bulk semimagnetic semiconductors of Cd 1− x Mn x Te for 0.04 ⊽ x ⩽ 0.36 at 2 K under nonresonant two-photon excitation.
Journal ArticleDOI
Josephson junctions based on amorphous MoGe: prospects for use in superconducting electronics
TL;DR: In this paper , all-MoGe Josephson junctions with a very thin Al/AlO x /(Al) barrier were fabricated and characterized, where the amorphous MoGe films exhibit superconducting transition temperatures up to 7 K. The experimental data on the temperature dependence of the subgap current agree well with theoretical calculations.
