Anomalous Nernst effect in perpendicularly magnetised τ-MnAl thin films
Daniel Scheffler, Sebastian Beckert, Helena Reichlova +3
-MnAl is interesting for spintronic applications as a ferromagnet with perpendicular magnetic anisotropy due to its high uniaxial magnetocrystalline anisotropy. Here we report o…
Extracting local switching fields in permanent magnets using machine learning
Markus Gusenbauer, Harald Oezelt, Johann Fischbacher +4
Microstructural features play an important role for the quality of permanent magnets. The coercivity is greatly influenced by crystallographic defects, which is well known for MnAl…
Thermoelectric determination of electronic entropy change in Ni-doped FeRh
Nicolás Pérez, Alisa Chirkova, Konstantin P. Skokov +5
The net entropy change corresponding to the charge carriers in a Ni-doped FeRh bulk polycrystal was experimentally evaluated in a single sample using low temperature heat capacity…
Role of twin and anti-phase defects in MnAl permanent magnets
Simon Bance, Florian Bittner, Thomas G. Woodcock +2
We quantify and explain the effects of both anti-phase boundaries and twin defects in as-transformed -MnAl by carrying out micromagnetic simulations based closely on the results…
Influence of defect thickness on the angular dependence of coercivity in rare-earth permanent magnets
Simon Bance, Harald Oezelt, Thomas Schrefl +12
The coercive field and angular dependence of the coercive field of single-grain NdFeB permanent magnets are computed using finite element micromagnetics. It is shown t…
