Generation of imprinted strain gradients for spintronics
Giovanni Masciocchi, Mouad Fattouhi, Elizaveta Spetzler +7
In this work, we propose and evaluate an inexpensive and CMOS-compatible method to locally apply strain on a Si/SiOx substrate. Due to high growth temperatures and different therma…
Strain effects on magnetic compensation and spin reorientation transition of Co/Gd synthetic ferrimagnets
Giovanni Masciocchi, Thomas J. Kools, Pingzhi Li +5
Synthetic ferrimagnets are an attractive materials class for spintronics as they provide access to all-optical switching of magnetization and, at the same time, allow for ultrafast…
Optimization of Permalloy properties for magnetic field sensors using He irradiation
Giovanni Masciocchi, Johannes Wilhelmus van der Jagt, Maria-Andromachi Syskaki +7
Permalloy, despite being a widely utilized soft magnetic material, still calls for optimization in terms of magnetic softness and magnetostriction for its use in magnetoresistive s…
Strain-controlled Domain Wall injection into nanowires for sensor applications
Giovanni Masciocchi, Mouad Fattouhi, Andreas Kehlberger +3
We investigate experimentally the effects of externally applied strain on the injection of 180 domain walls (DW) from a nucleation pad into magnetic nanowires, as typically…
Geometrical dependence of domain wall propagation and nucleation fields in magnetic domain wall sensor devices
B. Borie, A. Kehlberger, J. Wahrhusen +2
We study the key domain wall properties in segmented nanowires loop-based structures used in domain wall based sensors. The two reasons for device failure, namely the distribution…
Magnon mode selective spin transport in compensated ferrimagnets
Joel Cramer, Er-Jia Guo, Stephan Geprägs +10
We investigate the generation of magnonic thermal spin currents and their mode selective spin transport across interfaces in insulating, compensated ferrimagnet/normal metal bilaye…
Thermal generation of spin current in epitaxial CoFe2O4 thin films
Er-Jia Guo, Andreas Herklotz, Andreas Kehlberger +3
The longitudinal spin Seebeck effect (LSSE) has been investigated in high-quality epitaxial CoFe2O4 (CFO) thin films. The thermally excited spin currents in the CFO films are elect…
Origin of the thickness-dependent low-temperature enhancement of spin Seebeck effect in YIG films
Er-Jia Guo, Andreas Kehlberger, Joel Cramer +2
The temperature dependent longitudinal spin Seebeck effect (SSE) in heavy metal (HM)/ Y3Fe5O12 (YIG) bilayers is investigated as a function of different magnetic field strength, di…
Magnetic field control of the spin Seebeck effect
Ulrike Ritzmann, Denise Hinzke, Andreas Kehlberger +3
The origin of the suppression of the longitudinal spin Seebeck effect by applied magnetic fields is studied. We perform numerical simulations of the stochastic Landau-Lifshitz-Gilb…
Thermal conductance of thin film YIG determined using Bayesian statistics
C. Euler, P. Hołuj, T. Langner +4
Thin film YIG (YFeO) is a prototypical material for experiments on thermally generated pure spin currents and the spin Seebeck effect. The 3-omega method is an estab…
Origin of the spin Seebeck effect probed by temperature dependent measurements in GdFeO
Stephan Geprägs, Andreas Kehlberger, Tomek Schulz +10
We probe the spin Seebeck effect in GdFeO/Pt hybrid structures as a function of temperature and observe two sign changes of the spin Seebeck signal with decreasi…
Electronic properties of CoFeSi investigated by x-ray magnetic linear dichroism
Mirko Emmel, Alexey Alfonsov, Dominik Legut +11
We present experimental XMLD spectra measured on epitaxial (001)-oriented thin CoFeSi films, which are rich in features and depend sensitively on the degree of atomic order a…
Determination of the origin of the spin Seebeck effect - bulk vs. interface effects
Andreas Kehlberger, René Röser, Gerhard Jakob +9
The observation of the spin Seebeck effect in insulators has meant a breakthrough for spin caloritronics due to the unique ability to generate pure spin currents by thermal excitat…
