Direct demonstration of time-reversal-symmetry-breaking spin injection from a compensated magnet Open
The injection, propagation and detection of spin currents are essential physical processes in spintronics. So far, the separation of charge and spin currents was facilitated by the electrical spin injection from a ferromagnet (FM) or the i…

Dissipation properties of anomalous Hall effect: Intrinsic vs extrinsic magnetic materials Open
The power efficiency of Hall devices is still an open question. How is it possible to extract power from a current produced by the Hall effect? In what extent it is related to the nature of the effective magnetic field produced in the mate…

Dissipation properties of anomalous Hall effect: intrinsic vs. extrinsic magnetic materials Open
A comparative study of anomalous-Hall current injection and anisotropic current injection (through planar Hall effect) are studied in Hall devices contacted to a lateral load circuit. Hall currents are injected into the load circuit from t…

Observation of the anomalous Nernst effect in altermagnetic candidate Mn5Si3 Open
The anomalous Nernst effect generates a voltage transverse to an applied thermal gradient in some magnetically ordered systems. While the effect was considered excluded in compensated magnetic materials with collinear ordering, in the rece…

Magnetic aftereffect and Barkhausen effect in thin films of the altermagnetic candidate Mn5Si3 Open
Altermagnetism as a third distinct type of collinear magnetic ordering lately attracts vivid attention. We here study the Hall effect response of micron-scale Hall bars patterned into Mn5Si3 thin films, an altermagnet candidate material. R…

Altermagnetic variants in thin films of Mn5Si3 Open
The altermagnet candidate Mn5Si3 has attracted wide attention in the context of non-relativistic spin physics, due to its composition of light elements. However, the presumed structure of the altermagnetic phase had yet to be demonstrated.…

Anisotropy of the anomalous Hall effect in the altermagnet candidate Mn$_5$Si$_3$ films Open
Altermagnets are compensated magnets belonging to spin symmetry groups that allow alternating spin polarizations both in the coordinate space of the crystal and in the momentum space of the electronic structure. In these materials the anis…

A Novel Design of a 3D Racetrack Memory Based on Functional Segments in Cylindrical Nanowire Arrays Open
A racetrack memory is a device where the information is stored as magnetic domains (bits) along a nanowire (track). To read and record the information, the bits are moved along the track by current pulses until they reach the reading/writi…

Efficient Nanostructuring of Isotropic Gas-Atomized MnAl Powder by Rapid Milling (30 s) Open
An unprecedentedly short milling time of 30 s was applied to gas-atomized MnAl powder in order to develop permanent magnet properties and, in particular, coercivity. It is shown that such a short processing time followed by annealing resul…

Development of permanent magnet MnAlC/polymer composites and flexible filament for bonding and 3D-printing technologies Open
Searching for high-performance permanent magnets components with no limitation in shape and dimensions is highly desired to overcome the present design and manufacturing restrictions, which affect the efficiency of the final devices in ene…
