We present a detailed structural and magnetic characterization of sputter deposited thin film erbium, determined by x-ray diffraction, transport measurements, magnetometry and neutron diffraction. This provides information on the onset and change of the magnetic state as a function of temperature and applied magnetic field. Many of the features of bulk material are reproduced. Also of interest ...

In the past decades, neutron reflectometry have flourished as an applicable method to the study of thin films. As an example, the type and thickness of an unknown thin film which is mounted on top of a magnetic substratum could be determined by measuring the intensity and polarization of the reflected neutrons from the sample. Neutron reflectometry is based on solving the one dimentional schröd...

Superconducting thin films have the potential to overcome fundamental limitations of bulk niobium technology that is currently implemented in linear particle accelerators. Before these thin films can successfully be implemented, systematic studies on structureproperty correlations are necessary. Here, we present the characterization of niobium nitride thin films and multilayers. We explore the ...

In this work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...

thin film phthalocyanines(pc), incloding zinc, iron, and magnesium phthalocyani-nes, were prepared by vacuum deposition method. chronocoulometry was used to study the charge transfer reaction mechanism of ionic species through the thin films. the results obtained in chronocoulometric studies shows that the thin film phthalocyanines could operate via two mechanisms.the first mechanism metal pc t...

We theoretically investigate emergent quantum phases in the thin film geometries of the pyrochore iridates, where a number of exotic quantum ground states are proposed to occur in bulk materials as a result of the interplay between electron correlation and strong spin-orbit coupling. The fate of these bulk phases as well as novel quantum states that may arise only in the thin film platforms, ar...

mn doped zno nanocomposite thin film coated on glass by a simple spin-coating method was used to degrade an azo textile dye from aqueous environment. mn doped zno nanocomposite thin film was characterized by means of x-ray diffraction (xrd) and scanning electron microscopy (sem). the photo-reduction activity of photocatalyst was evaluated using an azo textile dye as organic contaminant irradiat...

Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...

Thin film samples of Ti-doped ZnO were grown on sapphire (0001) substrates by pulsed laser deposition (PLD). The magnetic moments were measured by SQUID magnetometry and the films were ferromagnetic at room temperature. The Faraday rotations and magnetic circular dichroisms (MCD) were measured as a function of energy at the range of 1.5-4 eV, and carrier concentrations were obtained from Hall e...

The magnetic flux penetration into thin type-II superconducting films with circular defects is investigated. The artificial circular defects ~diameter 540 mm) in an YBa2Cu3O72d thin film ~thickness '300 nm) were prepared by pulse-laser irradiation. The flux penetration into the zero-field-cooled superconducting film was visualized by means of the magneto-optic method. A stepwise increase of the...
