Temperature-driven microstructural, compositional, and magnetic changes in electrodeposited Fe-Pd thin films.

Thin layers of Fe50Pd50 were prepared by electrodeposition followed by thermal treatment to turn fcc structural anisotropy to fcf (tetragonal L10) structure with high uniaxial magnetocrystalline anisotropy. Very high coercivities were achieved by using low temperature thermal treatment, which prevents the negative influence of high temperature like grain growths and interdifusion.

A process for forming SiC ceramics by polymer route.

The development of the combined process for fabrication of SiC ceramics by electrophoretic deposition and pre-ceramic polymer infiltration and pyrolysis represent a novelty in the field of SiC-based structural materials. It enables preparation of SiC without the usually used sintering additives and at much lower temperatures than state-of-art processes. The material described in the paper has been proposed for application in future fusion reactor, where the purity of the material is of extreme importance.

Magnetoelasticity driven magnetic anisotropy changes in strained Sr2CrReO6.

Experimental results demonstrate large magneto-elastic properties and dependence of the magnteic anisotropy on the substrate crystalline phase. On the basis of ab-initio calculations a model, which relates the two properties, was proposed.

Self-organising of nanocrystals in desired 2D geometries.

We report on unusual crystallization phenomena that results in the self-assembly of sub-micron tubules of crystalline SrTiO3. The tubular structures were synthesized by EPD and annealing of SrTiO3 sols in the pores of anodized Al2O3 templates. Due to steric constraints the crystals self-organize in order to efficiently fill the available surface of the pore walls. The growth of nanocrystals inside constrained pores of the template and their subsequent oriented attachments, show the ability of crystal domains to adapt to spatial constraints and self-organize into polycrystalline morphologies.

Desorption of hydrogen from Ti-Zr-Ni hydrides using a mass spectrometer.

We have performed thermogravimetry (TG) and mass-spectrometry measurements of hydrogen desorbed from fully and partially hydrided ternary Ti–Zr–Ni amorphous, quasicrystalline and crystalline alloys, with four different initial compositions, where the Ti/Zr ratio ranged from 1 to 2.4. The TG measurements provided us with the mass% of desorbed hydrogen, whereas the mass-spectrometry revealed information about the hydrogen desorption temperatures in the material.
