Transport theory and spin-transfer physics in d-wave altermagnets
Ricardo Zarzuela, Rodrigo Jaeschke-Ubiergo, Olena Gomonay +2
We develop a mesoscale transport theory for the charge and spin degrees of freedom of itinerant carriers in a -wave altermagnet. Our effective Lagrangian description is built up…
Non-relativistic linear Edelstein effect in helical EuIn2As2
Nayra A. Álvarez Pari, Rodrigo Jaeschke-Ubiergo, Atasi Chakraborty +2
Motivated by the ongoing interest in understanding the actual magnetic ground state of the promising axion insulator candidate EuIn2As2, we present here a spin symmetry analysis an…
Highly Efficient Non-relativistic Edelstein effect in p-wave magnets
Atasi Chakraborty, Anna Birk Hellenes, Rodrigo Jaeschke-Ubiergo +3
The origin and efficiency of charge-to-spin conversion, known as the Edelstein effect (EE), has been typically linked to spin-orbit coupling mechanisms, which require materials wit…
Ultrafast electron dynamics in altermagnetic materials
Marius Weber, Kai Leckron, Luca Haag +4
Altermagnets constitute a new class of magnetic materials that combine properties previously thought to be exclusive to either antiferromagnets or ferromagnets, and have unique pro…
Observation of a non-reciprocal skyrmion Hall effect of hybrid chiral skyrmion tubes in synthetic antiferromagnetic multilayers
Takaaki Dohi, Mona Bhukta, Fabian Kammerbauer +12
A hybrid chiral skyrmion tube is a well-known example of a 3D topological spin texture, exhibiting an intriguing chirality transition along the thickness direction. This transition…
Altermagnetism: an unconventional spin-ordered phase of matter
T. Jungwirth, R. M. Fernandes, E. Fradkin +3
The Pauli exclusion principle combined with interactions between fermions is a basic mechanism across condensed-matter systems giving rise to a spontaneous breaking of the spin-spa…
