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…
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…
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…
