Direct demonstration of time-reversal-symmetry-breaking spin injection from a compensated magnet
Jone Mencos, Antonin Badura, Eoin Dolan +21
The injection, propagation and detection of spin currents are essential physical processes in spintronics. So far, the separation of charge and spin currents was facilitated by the…
Altermagnetic spintronics
T. Jungwirth, J. Sinova, P. Wadley +5
The research landscape of magnetism has been recently enriched by the discovery of altermagnetism. It is an unconventional phase of matter characterized by a d-wave (or higher even…
Quantum-impurity sensing of altermagnetic order
V. A. S. V. Bittencourt, Hossein Hosseinabadi, Jairo Sinova +2
Quantum sensing with individual spin defects has emerged as a versatile platform to probe microscopic properties of condensed matter systems. Here we demonstrate that quantum relax…
Switchable Exchange Bias Resulting from Correlated Domain Structures in Orthogonally Coupled Antiferromagnet/Ferromagnet van der Waals Heterostructures
Aditya Kumar, Sadeed Hameed, Thibaud Denneulin +8
Van der Waals (vdW) magnetic heterostructures offer a versatile platform for engineering interfacial spin interactions with atomic precision, enabling nontrivial spin textures and…
Symmetry, microscopy and spectroscopy signatures of altermagnetism
Tomas Jungwirth, Jairo Sinova, Rafael M. Fernandes +5
Altermagnetism is a collinear compensated magnetically-ordered phase with a d, g or i-wave anisotropy and alternating spin polarization of the electronic structure in the position…
Strain controlled g- to d-wave transition in altermagnetic CrSb
Bennet Karetta, Xanthe H. Verbeek, Rodrigo Jaeschke-Ubiergo +2
The possibility of a strain-induced transformation from -wave to -wave altermagnetism was recently recently proposed for MnTe using a perturbative model. In this w…
