Spin-canting effects in GMR sensors with wide dynamic field range
Clemens Muehlenhoff, Christoph Vogler, Wolfgang Raberg +2
Magnetoresistive (xMR) sensors find extensive application in science and industry, replacing Hall sensors in various low field environments. While there have been some efforts in i…
Microscopic origin of magnetization reversal in exchange-coupled ferro-/ferrimagnetic bilayers
Michael Heigl, Christoph Vogler, Andrada-Oana Mandru +4
In this study, the magnetic reversal process of exchange-coupled bilayer systems, consisting of a ferrimagnetic TbFeCo alloy layer and a ferromagnetic [Co/Ni/Pt]N multilayer, was i…
Hysteresis-free magnetization reversal of exchange-coupled bilayers with finite magnetic anisotropy
Christoph Vogler, Michael Heigl, Andrada-Oana Mandru +5
Exchange-coupled structures consisting of ferromagnetic and ferrimagnetic layers become technologically more and more important. We show experimentally the occurrence of completely…
Curie temperature modulated structure to improve the performance in heat-assisted magnetic recording
Olivia Muthsam, Christoph Vogler, Dieter Suess
We investigate how a temperature reduction in z-direction influences the switching probability and the noise in heat-assisted magnetic recording (HAMR) for a bit in bit-patterned m…
Stochastic ferrimagnetic Landau-Lifshitz-Bloch equation for finite magnetic structures
Christoph Vogler, Claas Abert, Florian Bruckner +1
Precise modeling of the magnetization dynamics of nanoparticles with finite size effects at fast varying temperatures is a computationally challenging task. Based on the Landau-Lif…
Noise reduction in heat-assisted magnetic recording by optimizing a high/low Tc bilayer structure
Olivia Muthsam, Christoph Vogler, Dieter Suess
It is assumed that heat-assisted magnetic recording (HAMR) is the recording technique of the future. For pure hard magnetic grains in high density media with an average diameter of…
