Ex situ analyses on topological insulator films require protection against surface contamination during air exposure. This work reports on a technique that combines deposition of protective capping just after epitaxial growth and its mechanical remov

Photoemission-intensity distributions I _RCP/LCP ( E _B , k ) measured for right- and left-circularly polarized soft x-rays revealed a large circular dichroism in angular distribution ( CDAD) in the 4D parameter space ( E _B binding energy, k momentu

Magnetic topological insulators are narrow-gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, magnetic topological insulators may have some of the surfaces gapped, which enabl

Ribbons of nominal composition (Pr9.5Fe84.5B6)0.96Cr0.01(TiC)0.03 were produced by arc-melting and melt-spinning the alloys on a Cu wheel. X-ray diffraction (XRD) reveals two main phases, one based upon α-Fe and the other upon Pr2Fe14B. The ribbons

Films of isotropic nanocrystalline Pd80Co20 alloys were obtained by electrodeposition onto brass substrate in plating baths maintained at different pH values. Increasing the pH of the plating bath led to an increase in mean grain size without inducin

Polycrystalline Ni nanowires were electrodeposited in nanoporous anodized alumina membranes with mean diameter of approximately 42 nm. Their magnetic properties were studied at 300 K, by measurements of recoil curves from demagnetized state and also

Polycrystalline Ni nanowires with different diameters were electrodeposited in nanoporous anodized alumina membranes. First-Order Reversal Curves (FORCs) were measured and FORC distributions were calculated. They clearly showed an asymmetric behavior

We observe an enhanced spin-polarization and a reduction of surface sensitivity due to intermediate unoccupied electronic states in spin-resolved two-photon photoemission (2PPE) from ferromagnetic cobalt films. We discriminate 2PPE signals coming fro

It was realized at the very beginning of the development of the quantum theory of condensed matter that, although solids are composed of atoms, they cannot be described using atomic properties only. The reason lies in the collective phenomena that ap
