Structural transformation and magnetic properties of (FeCo)B alloys doped with 5 elements: A combined first-principles and experimental study
A. Musiał, W. Marciniak, Z. Śniadecki +8
(Fe,Co)B-based compounds with specified 5 substitutions are considered as promising materials for permanent magnets without rare-earth elements. We conducted a combined firs…
Magnetocaloric effect and scaling analysis in superspin glass Co/Au nanoparticles
P. Hrubovcak, A. Zelenakova, V. Zelenak +2
Bimetallic Co/Au (core/shell) nanoparticle system exhibiting transition form superparamagnetic (SPM) to superspin glass state (SSG) at low temperatures has been investigated with r…
Biasing the ferronematic - a new way to detect weak magnetic field
Natalia Tomasovicova, Jozef Kovac, Yuriy Raikher +6
Magnetic properties of a ferronematic, i.e., nematic liquid crystal doped with magnetic nanoparticles in low volume concentration are studied, with the focus on the ac magnetic sus…
Magnetoresistance of composites based on graphitic disks and cones
Jozef Černák, Geir Helgesen, Fredrik Sydow Hage +1
We have studied the magnetotransport of conical and disk-shaped nanocarbon particles in magnetic fields at temperatures $2\leq T\leq300\:\mathrm{K…
Structural and Magnetic Properties of CoO-Pt core-shell nanoparticles
Adriana Zelenakova, Vladimir Zelenak, Stefan Michalik +2
Using microemulsion methods, CoO-Pt core-shell nanoparticles (NPs), with diameters of nominally 4 nm, were synthesized and characterized by high-resolution transmission electron mi…
AC Losses of Copper Stabilized Multifilament YBCO Coated Conductors
G. A. Levin, J. Murphy, T. J. Haugan +3
We report the data on magnetization losses and critical current of multifilament copper stabilized coated conductors. Eight centimeters long samples of copper stabilized YBa2Cu3O7-…
Magnetic properties of carbon nanodisk and nanocone powders
Jozef Cernak, Geir Helgesen, Jozef Kovac +2
We have investigated the magnetic properties of carbon powders which consist of nanodisks, nanocones, and a small fraction of carbon-black particles. Magnetization measurements wer…
Evolution of the fishtail-effect in pure and Ag-doped MG-YBCO
D. A. Lotnyk, R. V. Vovk, M. A. Obolenskii +8
We report on magnetic measurements carried out in a textured YBaCuO and YBa(CuAg)O (at 0.02) crystals. The so-called fishtai…
Radiation stability of biocompatibile magnetic fluid
Natalia Tomasovicova, Ivan Haysak, Martina Koneracka +7
The radiation stability of biocompatibile magnetic fluid used in nanomedicine after electron irradiation was studied. Two types of the water-based magnetic fluids were prepared. Th…
Influence of aging on fishtail-effect in pure and Ag-doped MG-YBCO
D. Lotnyk, R. V. Vovk, M. A. Obolenskii +7
-curves were experimentally investigated. Fishtail-effect (FE) was observed in MG YBaCuO and YBa(CuAg)O (at 0.02) crys…
Anomalous magnetoresistance of EuBC: Enhancement of magnetoresistance in systems with magnetic polarons
M. Batkova, I. Batko, K. Flachbart +8
We present results of measurements of electrical, magnetic and thermal properties of EuBC. The observed anomalously large negative magnetoresistance as above, so…
