Altermagnetic lifting of Kramers spin degeneracy
J. Krempaský, L. Šmejkal, S. W. D'Souza +20
Lifted Kramers spin-degeneracy has been among the central topics of condensed-matter physics since the dawn of the band theory of solids. It underpins established practical applica…
Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs
Tomas Janda, Joao Godinho, Tomas Ostatnicky +23
Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microsco…
Quenching of an antiferromagnet into high resistivity states using electrical or ultrashort optical pulses
Zdeněk Kašpar, Miloslav Surýnek, Jan Zubáč +16
Ultra-fast dynamics, insensitivity to external magnetic fields, or absence of magnetic stray fields are examples of properties that make antiferromagnets of potential use in the de…
THz electrical writing speed in an antiferromagnetic memory
K. Olejnik, T. Seifert, Z. Kaspar +11
The speed of writing of state-of-the-art ferromagnetic memories is physically limited by an intrinsic GHz threshold. Recently, an alternative research direction has been initiated…
