Spin Hall Magnetoresistance in Antiferromagnetic Insulators
Stephan Geprägs, Matthias Opel, Johanna Fischer +4
Antiferromagnetic materials promise improved performance for spintronic applications, as they are robust against external magnetic field perturbations and allow for faster magnetiz…
Gate-controlled skyrmion and domain wall chirality
Charles-Elie Fillion, Johanna Fischer, Raj Kumar +14
Magnetic skyrmions are localized chiral spin textures, which offer great promise to store and process information at the nanoscale. In the presence of asymmetric exchange interacti…
Patterning enhanced tetragonality in BiFeO3 thin films with effective negative pressure by helium implantation
C. Toulouse, J. Fischer, S. Farokhipoor +13
Helium implantation in epitaxial thin films is a way to control the out-of-plane deformation independently from the in-plane strain controlled by epitaxy. In particular, implantati…
Domain switching and exchange bias control by electric field in multiferroic conical magnet MnGeO
Jonas K. H. Fischer, Hiroki Ueda, Tsuyoshi Kimura
The electric field effect on magnetism was examined in the multiferroic conical magnet MnGeO, which shows a strong coupling between ferromagnetic and ferroelectric order pa…
Spin Hall magnetoresistance in antiferromagnetic insulators
Stephan Geprägs, Matthias Opel, Johanna Fischer +5
Antiferromagnetic materials promise improved performance for spintronic applications, as they are robust against external magnetic field perturbations and allow for faster magnetiz…
A journey into the tuneable antiferromagnetic spin textures of BiFeO3
A. Haykal, J. Fischer, W. Akhtar +10
Antiferromagnetic thin films are currently generating considerable excitement for low dissipation magnonics and spintronics. However, while tuneable antiferromagnetic textures form…
Large spin Hall magnetoresistance in antiferromagnetic α-Fe2O3/Pt heterostructures
Johanna Fischer, Matthias Althammer, Nynke Vlietstra +5
We investigate the spin Hall magnetoresistance (SMR) at room temperature in thin film heterostructures of antiferromagnetic, insulating, (0001)-oriented alpha-Fe2O3 (hematite) and…
Spin Hall magnetoresistance in antiferromagnet/heavy-metal heterostructures
Johanna Fischer, Olena Gomonay, Richard Schlitz +8
We investigate the spin Hall magnetoresistance in thin film bilayer heterostructures of the heavy metal Pt and the antiferromagnetic insulator NiO. While rotating an external magne…
