Ensembles of crystals of thin-plate martensite initiated by a strong magnetic field are analyzed within the concepts of the dynamic theory. It is shown that the laws detected agree with a specific dislocation scheme of arrangement of austenite subgrains with orientation {110}γ. © 2014, Springer Science+Business Media New York. / The work has been p...

Controlled manipulation of neutron spin is a critical tool for many neutron scattering techniques. We have constructed current-sheet, neutron spin flippers for use in Spin Echo Scattering Angle Measurement (SESAME) that comprise pairs of open-faced solenoids which introduce an abrupt field reversal at a shared boundary. The magnetic fields generate...
In this paper we apply and discuss a method for the determination of the magnetic field (H) evolution in supernova remnants (SNRs) from radio luminosity at given frequency v to diameter (Lv - D) correlation. We assumed that H evolves as H ∞ D-δ, where D is the diameter of the remnant. A value δ 
1.2 is obtained under the equipartition assumption fr...
The magnetic hyperfine field and electric-field gradient at isolated lanthanide impurities in an Fe host lattice are calculated from first principles, allowing for the first time a qualitative and quantitative understanding of an experimental data set collected over the past 40 years. It is demonstrated that the common Local Density Approximation l...

Modelling of steady-state magneto-convective flows has been performed for typical geometries of currently investigated Helium-Cooled Lithium Lead (HCLL) blankets. For fusion relevant magnetic fields the flow has been studied for a purely diffusive heat transfer regime and for a convective regime with finite Peclet number. The effect of the directio...

In this thesis with pulsed laser deposition Nd-Fe-B layers were deposited. The Nd-Fe-B layers were deposited both on chromium and on tantalum buffers. The layers, which were deposed on tantalum buffers, showed a strong dependence of the nicrostructure and the magnetic properties on the deposition temperature. On layers which were deposited at depos...
