Influence of the Néel vector on the bulk electronic structure of MnTe measured from the surface
D. A. Usanov, A. B. Hellenes, S. Hahn +7
Altermagnetism gives rise to momentum-dependent spin splitting without net magnetization. Here, we use angle-resolved photoemission spectroscopy (ARPES) to investigate bulk -MnT…
Reversible field-free superconducting diode effect controlled by an antiferromagnet
Filip Krizek, Kamil Olejník, Tobias Edwinson +19
The semiconductor diode, which allows current to flow preferentially in one direction, is a fundamental building block of numerous modern electronic circuits. Its superconducting a…
Ferroelectric -wave magnets
Jan Priessnitz, Anna Birk Hellenes, Riccardo Comin +1
Couplings between ferroelectric and magnetic orders offer promising routes toward low-dissipation electronics. However, such couplings are notably rare, largely due to the poor com…
Persistent altermagnetism
Warlley H. Campos, F. C. Fobasso Mbognou, Anna Birk Hellenes +4
Persistent spin textures with collinear spin polarization are promising platforms for spintronics applications. However, their typically relativistic spin-orbit origin leads to wea…
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…
Unconventional relativistic spin polarization of electronic bands in an altermagnet
A. Dal Din, D. A. Usanov, L. Šmejkal +22
Altermagnetism is a recently identified phase with a d, g or i-wave spin symmetry of magnetic ordering. Its discovery opens new research fronts at intersections of magnetism and sp…
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…
Anomalous Nernst effect in the noncollinear antiferromagnet MnSi
Christoph Sürgers, Gerda Fischer, Warlley H. Campos +6
Investigating the off-diagonal components of the conductivity and thermoelectric tensor of materials hosting complex antiferromagnetic structures has become a viable method to reve…
Observation of the anomalous Nernst effect in altermagnetic candidate Mn5Si3
Antonin Badura, Warlley H. Campos, Venkata K. Bharadwaj +20
The anomalous Nernst effect generates transverse voltage to the applied thermal gradient in magnetically ordered systems. The effect was previously considered excluded in compensat…
Direct observation of altermagnetic band splitting in CrSb thin films
Sonka Reimers, Lukas Odenbreit, Libor Smejkal +14
Altermagnetism represents an emergent collinear magnetic phase with compensated order and an unconventional alternating even-parity wave spin order in the non-relativistic band str…
P-wave magnets
Anna Birk Hellenes, Tomáš Jungwirth, Rodrigo Jaeschke-Ubiergo +3
The p-wave Cooper-pairing instability in superfluid He, characterized by a parity-breaking excitation gap, is regarded as one of the most rich and complex phenomena in physic…
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…
Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO
O. Fedchenko, J. Minar, A. Akashdeep +20
Altermagnets are an emerging third elementary class of magnets. Unlike ferromagnets, their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they pr…
Giant and tunneling magnetoresistance effects from anisotropic and valley-dependent spin-momentum interactions in antiferromagnets
Libor Šmejkal, Anna Birk Hellenes, Rafael González-Hernández +2
Giant or tunneling magnetoresistance are physical phenomena used for reading information in commercial spintronic devices. The effects rely on a conserved spin current passing betw…
