Ternary Heusler compounds form a numerous class of intermetallics, which include two families with general compositions ABC and AB2C, usually referred to as half- and full-Heusler compounds, respectively. Given their tunable electronic properties, made possible by adjusting the chemical composition, these materials are currently considered for...

Abstract View references (12) A microelectromechanical system (MEMS) entirely made of crystalline oxides is presented. A suspended SrTiO3 (001) microcantilever is employed as flexible substrate for the deposition of epitaxial transition-metal oxide films. A strain-generator device for epitaxial oxide films can be fabricated. Strain at surface...

In this work, the feasibility condition of Powder-In-Tube (PIT) processed wires of Fe(Se,Te) superconductor has been investigated. We faced several technical issues that are extensively described and discussed. In particular, we tested different metals and alloys as external sheaths (Cu, Ag, Nb, Ta, Ni, Fe, cupronickel, brass) concluding that...

We fabricate and characterize silver (Ag) line patterns obtained by means of the drop-on-demand inkjet printing technique. We use a very simple and cost-effective reduction reaction of silver nitrate (AgNO3) aqueous solution deposited on different substrates, namely flexible polyimide (Kapton®), alumina and insulating glass ceramics (Macor®)....

The study of overdoped FeTe1-xSex (0.5 < x < 1) polycrystalline superconductor samples is reported. The samples were prepared using a melting technique previously developed by our group. Increasing the Se content a phase separation related to the formation of FeSe inside the Fe(Se,Te) phase happens, as demonstrated by structural analysis and...

An increasing number of cryogenic devices may benefit from the use of Nd2Fe14B permanent magnets. However, it is necessary to precisely know their behavior because magnetization varies significantly due to Spin Reorientation Transition. In this work, magnetic and morphological characterization of Nd2Fe14B commercial polycrystalline magnets with...

The crystal structure of the new ternary ThNi6Si6 and UNi6Si6 intermetallic compounds has been investigated by means of both single crystal and powder X-ray diffraction followed by Rietveld refinement. Both compounds adopt the tetragonal CeNi6Si6-type structure, crystallizing in the space group P4/nbm (No. 125) (Pearson's symbol tP52). This...
