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…
A 54-filamentary CuZn sheathed MgB2 wires produced by Hyper Tech Inc. were used to make a 12 strand cable of 0.70 – 0.76 mm thickness. The individual wires were wrapped around a core, obtaining a rectangular cross-section cable (so-called Rutherford cable, Fig.1). The threshold of engineering current density Je = 104 Acm-2 for the cable…
A new automated external defibrillator (AED) has been installed at our institute and is located at the reception desk near the entrance door. In case of an emergency, it is necessary to immediately contact the emergency number 155, which will coordinate the response and ensure access to the defibrillator through a trained staff member. We…

Composite tape conductors containing the high-temperature superconductor REBCO, deposited in a thin layer (1-2 µm) on a metal substrate and covered with a protective layer of silver and copper, are being considered for future accelerators and fusion reactors. It turns out, however, that it will be necessary to reduce the magnetic hysteresis (energy dissipation) by…
The Institute of Electrical Engineering SAS announces a selection procedure for the position of Research Scientist at the Department of Physics and Technology at Nanoscale. Job Information: The position will focus on independent scientific research in the field of the development of artificial magnetic crystals and will include the fabrication of artificial magnetic structures, the…
Reduction of energy and material losses caused by friction (tribological phenomena) in inert, vacuum, or chemically aggressive environments and in microscale systems requires dry lubricant systems since the classical liquid lubricants lose their efficiency in such conditions. The most promising lubricants for these applications include two-dimensional layered crystals of MoS2, graphene, or hexagonal-BN. However, modification…
A mid-term review meeting took place this week as a part of the ongoing strategic collaboration between the Institute of Electrical Engineering of the Slovak Academy of Sciences (IEE SAS), Taiwan’s Industrial Technology Research Institute (ITRI), and the Slovak University of Technology (STU). The partners reviewed the achievements of the past two years and discussed…
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…
The Selection Committee for the election of the Director of the Institute of Electrical Engineering Slovak Academy of Sciences (IEE SAS) and the Scientific Board of IEE SAS invite you all to the presentation of the candidate for the position of Director of the IEE SAS – Ing. Milan Ťapajna, PhD., which will take place on November…
