Quantum Magnetism and Nanophysics (QMAGNA)

Ten years ago, Ising superconductivity was discovered in a single layer of NbSe₂, which has unique quantum properties and could be used, for example, in the development of topological quantum computers. A typical feature of this phenomenon is that superconductivity can withstand extremely strong magnetic fields if they are oriented parallel to the layer. However, … Continued

In the present article, we studied the catalytic activity of magnetron-sputtered MoxNiyXz (where X = Al, Co, Cr, Cu, Fe, W) thin films for the hydrogen evolution reaction (HER) in 1 M NaOH. Thin-film electrocatalysts were prepared at 25 °C and 800 °C and characterized by SEM-EDX and XRD analyses. The Mo80Ni5Al15(800 °C)   electrocatalyst demonstrated … Continued

The phenomena at the interface of two different materials can differ significantly from the properties of the original materials. In our last work, we showed that a superconducting state is observed at the interface of a topological insulator Bi2Te3 with a thickness of 300 nm and a non-superconducting material FeTe with a thickness of one … Continued

MXenes, as 2D materials derived from graphene, are excellent candidates for medical applications e. g. tomography and magnetic resonance imaging. However, their utilization is limited by their diamagnetic nature. In this work the MXene was functionalized by Gd(III) ions providing magnetic response. The resultant Gd-MXene displays paramagnetic response necessary for T1 – MR imaging. In … Continued

 In the present article, we studied the catalytic activity of magnetron sputtered Mo, V, Ni, and Co thin films for hydrogen evolution reaction (HER) in the alkaline electrolyte. We have observed for some metals a very large increase of HER activity for thin films sputtered at elevated temperatures when compared metals sputtered at room temperature. … Continued

Glasses are materials that are characterized by a disordered structure. The study of glasses is not only interesting from a practical point of view but also for its fundamental properties. Glasses are characterized by “universal anomalous behavior” that is not observed in ordered structures at very low temperatures. They are, for example, the boson peak … Continued
