Why April 14? This date is derived from Planck’s constant 4.14 (4.1356677×10⁻¹⁵ eV·s). This constant is the basis of quantum theory and defines the smallest units of energy. https://www.worldquantumday.org It is also a very practical constant, in addition to defining the international unit of the kilogram, it plays a key role in the design of…
Artificial magnetic structures with periodic magnetic ordering – artificial magnetic crystals – are potential media for magnetic waves. Creating order in artificial 2D magnetic structures is problematic due to the large energy barriers between many metastable states. We have studied the reduction of these energy barriers by applying an out-of-plane magnetic field. The out-of-plane field partially rotates the magnetic…
In 2025, researchers from the Institute of Electrical Engineering of the Slovak Academy of Sciences, presented their scientific activities as part of the European Researchers’ Night festival. Since 2025 was also declared the International Year of Quantum Science and Technology, a Quantum Zone was created in the V-club, featuring demonstrations, experiments, and workshops. At our…
A thin TiO2 semiconductor layer embedded between two metal electrodes is known to work as a memory cell, the famous memristor. To work as a memristor, the structure is formed by soft breakdown which creates a conducting nano-filament penetrating through the poorly conducting TiO2 and connecting the electrodes conductively. Previous works determined the number of…
