Natančno merjenje specifične upornosti v materialih nizke upornosti predstavlja izziv zaradi vpliva parazitnih upornosti merilnih vodnikov in kontaktov. V tej zaključni nalogi opisujem implementacijo, sistematično vrednotenje in uporabo Van der Pauw metode, ki omogoča natančne meritve na vzorcih pol ...

Oznake: kristalne strukture;kvazi kristali;energetska stabilnost;
This paper presents a detailed density functional theory study of the 1/1 periodic approximant Zn-Mg-Hf crystal structure, which is a close analog of the F-type Bergman-type quasicrystal. Two structural models, Bergman-like and Tsai-like, are examined to investigate their energetic stability, electr ...

Oznake: kvazikristali;quasicrystals;
New quasicrystals with rare-earth elements and Li are synthesized with the selfflux method. The starting composition involves 62.8 at.% Zn, 28.6 at.% Mg, 3.6 at. % rare-earth and 5% Li. Alternatively, 66 at.% Zn, 24.8 at.% Mg, 3.9 at.% rare-earth and 5.3% Li can be used. Both syntheses result in qua ...

This study presents the atomic structure solution of a primitive icosahedral Zn70.83Mg20.31Er8.86 quasicrystal using in-house X-ray diffraction and the Ammann–Kramer–Neri tiling framework. The structural model with 344 parameters refined against 2674 Bragg peaks achieves a reasonable R factor of 0.1 ...

We have determined the crystal structure and the magnetic state of the CeFe9Si4 intermetallic compound. Our revised structural model (fully ordered tetragonal unit cell, I4/ mcm) agrees with the previous literature report, except for some minor quantitative differences. Magnetically, the CeFe9Si4 un ...

Oznake: high-entropy alloys;structure and microstructure;superconductivity;
In this study, we investigate the scandium-containing Sc-Hf-Nb-Ta-Ti-Zr system of refractory high-entropy alloys (HEAs). Using the arc-melting method, we synthesized nine equimolar alloys (five 4-, three 5- and one 6-component), with all of them containing Sc. The alloys were characterized by XRD, e ...
