Switching field distribution of exchange coupled ferri-/ferromagnetic composite bit patterned media
Harald Oezelt, Alexander Kovacs, Johann Fischbacher +6
We investigate the switching field distribution and the resulting bit error rate of exchange coupled ferri-/ferromagnetic bilayer island arrays by micromagnetic simulations. Using…
Micromagnetic simulation of exchange coupled ferri-/ferromagnetic composite in bit patterned media
Harald Oezelt, Alexander Kovacs, Phillip Wohlhüter +6
Ferri-/ferromagnetic exchange coupled composites are promising candidates for bit patterned media because of the ability to control the magnetic properties of the ferrimagnet by it…
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…
Numerical optimization of writer and media for bit patterned magnetic recording
A. Kovacs, H. Oezelt, M. E. Schabes +1
In this work we present a micromagnetic study of the performance potential of bit-patterned (BP) magnetic recording media via joint optimization of the design of the media and of t…
