Static magnetic proximity effects and spin Hall magnetoresistance in Pt/YFeO and inverted YFeO/Pt bilayers

Stephan Geprägs, Christoph Klewe, Sibylle Meyer +13

The magnetic state of heavy metal Pt thin films in proximity to the ferrimagnetic insulator YFeO has been investigated systematically by means of x-ray magnetic…

Superchiral photons unveil magnetic circular dichroism

S. W. Lovesey, J. T. Collins, S. P. Collins

Polarization-dependent photon spectroscopy (dichroism) using signal-enhancing superchiral beams is shown to be sensitive to magnetic properties of the sample, whereas previous inve…

Investigation into the role of the orbital moment in a series of isostructural weak ferromagnets

D. Pincini, F. Fabrizi, G. Beutier +10

The orbital contribution to the magnetic moment of the transition metal ion in the isostructural weak ferromagnets ACO (A=Mn,Co,Ni) and FeBO was investigated by a combinati…

Direct observation of electron density reconstruction at the metal-insulator transition in NaOsO3

N. Gurung, N. Leo, S. P. Collins +10

5d transition metal oxides offer new opportunities to test our understanding of the interplay of correlation effects and spin-orbit interactions in materials in the absence of a si…

A unified formulation of dichroic signals using the Borrmann effect and twisted photon beams

Stephen P Collins, Stephen W Lovesey

Dichroic signals derived from the Borrmann effect and a twisted photon beam with topological charge l = 1 are formulated with an effective wavevector. The unification applies for n…
