Tuning the coexistence regime of incomplete and tubular skyrmions in ferro/ferri/ferromagnetic trilayers
Oguz Yildirim, Riccardo Tomasello, Yaoxuan Feng +8
The development of skyrmionic devices requires a suitable tuning of material parameters in order to stabilize skyrmions and control their density. It has been demonstrated recently…
Mapping the Structure of Oxygen-Doped Wurtzite Aluminum Nitride Coatings From Ab Initio Random Structure Search and Experiments
Piero Gasparotto, Maria Fischer, Daniele Scopece +8
Machine learning is changing how we design and interpret experiments in materials science. In this work, we show how unsupervised learning, combined with ab initio modeling, improv…
Coexistence of distinct skyrmion phases observed in hybrid ferromagnetic/ferrimagnetic multilayers
Andrada-Oana Mandru, Oğuz Yıldırım, Riccardo Tomasello +6
Materials hosting magnetic skyrmions at room temperature could enable new computing architectures as well as compact and energetically efficient magnetic storage such as racetrack…
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…
Halbach arrays at the nanoscale from chiral spin textures
Miguel A. Marioni, Marcos Penedo, Mirko Baćani +2
Mallinson's idea that some spin textures in planar magnetic structures could produce an enhancement of the magnetic flux on one side of the plane at the expense of the other gave r…
Surface single-molecule dynamics controlled by entropy at low temperatures
Jeffrey C. Gehrig, Marcos Penedo, Manfred Parschau +4
Configuration transitions of individual molecules and atoms on surfaces are traditionally described with energy barriers and attempt rates using an Arrhenius law. This approach yie…
How to measure the local Dzyaloshinskii Moriya Interaction in Skyrmion Thin Film Multilayers
Mirko Baćani, Miguel A. Marioni, Johannes Schwenk +1
The current driven motion of skyrmions in MnSi and FeGe thinned single crystals could be initiated at current densities of the order of A/m, five orders of magnitude smaller…
Bimodal Magnetic Force Microscopy with Capacitive Tip-Sample Distance Control
Johannes Schwenk, Xue Zhao, Mirko Baćani +3
A single-passage, bimodal magnetic force microscopy technique optimized for scanning samples with arbitrary topography is discussed. A double phase-locked loop (PLL) system is used…
Role of interface coupling inhomogeneity in domain evolution in exchange bias
Andrea Benassi, Miguel A. Marioni, Daniele Passerone +1
Models of exchange-bias in thin films have been able to describe various aspects of this technologically relevant effect. Through appropriate choices of free parameters the modelle…
Force-distance studies with piezoelectric tuning forks below 4.2 K
J. Rychen, T. Ihn, P. Studerus +5
Piezoelectric quartz tuning forks have been employed as the force sensor in a dynamic mode scanning force microscope operating at temperatures down to 1.7 K at He-gas pressures of…
