Ultrathin (111)-oriented polar iron oxide films were grown on a Pt(111) single crystal either by the reactive deposition of or oxidation metallic monolayers. These characterized using low energy electron diffraction, scanning tunneling microscopy and conversion Mossbauer spectroscopy. The Fe led to island growth Fe3O4, in which electronic magnetic properties bulk material modulated superparamagnetic size effects for thicknesses below 2 nm, revealing specific surface interface features. In...
We report on in-plane magnetic anisotropy in epitaxial bcc Co/Fe(110) bilayers W(110). The surface the exhibited a strong nonmonotonic dependence Co coverage. Magneto-optical studies revealed sharp maximum of anisotropy, $2.44\phantom{\rule{0.16em}{0ex}}\mathrm{mJ}/{\mathrm{m}}^{2}$, at ${d}_{\mathrm{Co}}=5\phantom{\rule{0.16em}{0ex}}\AA{}$. This giant interfacial allowed small fraction monolayer to reorient magnetization bulk-like Fe film. conclude that mono- and double-layer Co(110) with...
This comprehensive work showcases two novel, rock-salt-type minerals in the form of amphoteric cerium-tungstate double perovskite and ilmenite powders created via a high-temperature solid-state reaction inert gases. The presented studies have fundamental meaning will mainly focus on detailed synthesis description undoped structures, researching their possible polymorphism various conditions hinting at some nontrivial physicochemical properties like charge transfer for upcoming optical after...
Nuclear resonant scattering (NRS) of synchrotron radiation was used to investigate the magnetic anisotropy iron films in MgO/Fe(t)/MgO(001) structures for t = (4–10) Å. The low-temperature NRS spectra were analyzed using a static magnetization model involving two interface-like components and bulk-like component. We confirmed existence perpendicular MgO/Fe/MgO at 10 K with an increasing in-plane component > 8 Å over entire thickness Fe film. evolution structure temperature studied...
Adsorption of oxygen on the (110) surface epitaxial iron films tungsten was studied using low-energy electron diffraction (LEED), microscopy (LEEM), and Auger spectroscopy within an exposure range 0–300 Langmuir (L). Selected adsorption structures Fe(110) reported in literature were critically compared revised reference to present study. The initial 1/4 monolayer resulting commonly observed (2 × 2) structure followed by a that frequently termed as (3 1). Its complex LEED pattern ultimately...
The synchrotron radiation facility ‘Solaris’ is currently being built in Krakow, Poland. first experimental beamline at Solaris will use bending magnet and two exchangeable end stations: a spectroscopic X‐ray photoemission electron microscope soft absorption spectroscopy chamber. We present the specifications exemplary results obtained with our station microscope, which ( statu nascendi of Solaris) has been operated NanoXAS Swiss Light Source. stations should be available for broad user...
Systematic studies of the two high-temperature monolayer oxygen structures that exist on (110) tungsten surface were performed using low-energy electron microscopy and diffraction measurements. Our work questions commonly accepted interpretation from literature striped superstructures arise alternating site-exchanged (S-E) domains. We postulate originate a misfit between lattices while appearance corresponds to moir\'e pattern. Moreover, we show structures, indicated as 113- 337-phases due...
We report on a custom-built UHV-compatible Magneto-Optical Kerr Effect (MOKE) magnetometer for applications in surface and materials sciences, operating tandem with the PhotoEmission Electron Microscope (PEEM) endstation at Nanospectroscopy beamline of Elettra synchrotron.

Longitudinal polar MOKE measurement geometries are realized. magneto-optical...
We studied the formation of alloys and compounds Eu-Fe binary system, in form thin films, prepared using molecular beam epitaxy. Diffraction photoelectron spectroscopy investigations revealed mixing elements during annealing at relatively low temperature. Magnetic studies showed ferromagnetic behavior up to 400 K, strong thermomagnetic effects exchange bias indicating presence an antiferromagnetic phase superparamagnetic particles. X-ray photoemission microscopy with dichroic contrast...
