Journal ArticleDOI
Ultrasonic instrumentation for measurements in high magnetic fields. I. Continuous magnetic fields
TL;DR: In this article, the authors describe a basic ultrasonic system intended for measurements in quasicontinuous fields, which operates in the frequency range from 10 to 1000 MHz and enables precise measurements of changes in the ultrasonic velocity and attenuation in solids using the pulse echo technique.
Journal ArticleDOI
Critical fields and Landau-Ginzburg parameters of the heavy-fermion superconductor UPt3.
TL;DR: Measurements of both the lower and upper critical fields along all three principal axes of the heavy-fermion superconductor UPt{sub 3} have been performed and a kink in the temperature dependence of the lower critical field is observed for all three orientations, in agreement with a recent theory.
Journal ArticleDOI
Ferrimagnetism in strained Fe2As thin films on Si(001)
TL;DR: In this paper, the structural and magnetic properties of Fe2As thin films grown on Si(100) by molecular beam epitaxy were analyzed using high-energy electron diffraction and x-ray diffraction patterns.
Journal ArticleDOI
Distribution of vortices in Nb/Al multilayers studied by spin-polarized neutron reflectivity and magnetization
Sang-Wook Han,John Farmer,Paul F. Miceli,G. P. Felcher,R. Goyette,G. T. Kiehne,John B Ketterson +6 more
TL;DR: In this article, the authors present SPNR and DC magnetization studies of non-uniformly distributed vortices in Nb/Al multilayers for fields applied near-parallel to the film surface.
Journal ArticleDOI
Anisotropic properties of sinter-forged YBa2Cu3O7-σ
TL;DR: In this paper, an analysis based on the Ginzburg-Landau theory, combined with a Gaussian fit to the measured angular distribution function of the crystallites, was carried out.
