Micromagnetics of rare-earth efficient permanent magnets
Johann Fischbacher, Alexander Kovacs, Markus Gusenbauer +4
The development of permanent magnets containing less or no rare-earth elements is linked to profound knowledge of the coercivity mechanism. Prerequisites for a promising permanent…
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…
Thermal activation in permanent magnets
Simon Bance, Johann Fischbacher, Alexander Kovacs +3
The coercive field of permanent magnets decays with temperature. At non-zero temperature the system can overcome a finite energy barrier through thermal fluctuations. Using finite…
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…
Grain-size dependent demagnetizing factors in permanent magnets
Simon Bance, Bernhard Seebacher, Thomas Schrefl +10
The coercive field of permanent magnets decreases with increasing grain size. The grain size dependence of coercivity is explained by a size dependent demagnetizing factor. In Dy f…
Hard magnet coercivity
S. Bance, G. Ciuta, T. Shoji +7
Based on a critical analysis of the experimental coercive properties, general considerations on the reversal mechanisms in RFeB magnets are recalled. By plotting together the exper…
