Variation in ferromagnetic domain density and domain asymmetry in Fe / FeF 2 exchange bias structures
S. Widuch,S. Widuch,S. Widuch,Zbigniew Celinski,K. Balin,K. Balin,Rudolf Schäfer,Ludwig Schultz,D. Skrzypek,Jeffrey McCord +9 more
TL;DR: In this article, the development of ferromagnetic domains in exchange-coupled bilayers was studied by magneto-optical magnetometry and microscopy in a temperature range from 300 to 17 K.

Optimization of magneto-optical response of FeF2/Fe/FeF2 sandwiches for microwave field detection
R. Lopusnik,James Correu,Ian Harward,S. Widuch,Paweł Maślankiewicz,Sezen Demirtas,Zbigniew Celinski,Eva Liskova,Martin Veis,Stefan Visnovsky +9 more
TL;DR: In this article, the magneto-optical (MO) response of dielectric/Fe/dielectric sandwich structures for microwave B-field sensor applications was investigated.

Eu valence in ultra-thin layers of EuF3 derived from photon energy dependent photoemission and photoabsorption
Jacek Szade,W. Burian,Marco Zangrando,Federica Bondino,Elena Magnano,S. Widuch,S. Widuch,Zbigniew Celinski +7 more
TL;DR: In this paper, it was shown that Eu valence derived from the XAS and RESPE spectra depends on photon energy and is dominated by the final state effects for the 4d-4f resonance.

Dynamic and Rotatable Exchange Anisotropy in Fe/KNiF3/FeF2 Trilayers
TL;DR: In this article, the results from ferromagnetic resonance experiments carried out on epitaxially grown Fe/KNiF3/FeF2 trilayers are presented, and three thickness regimes appear that correspond to different values of exchange bias in each region.
