Uncovering domain morphology in an unconventional magnet with scanning diamond quantum magnetometry
Freya Johnson, Jan Zemen, Helena Knowles +1
Unconventional magnetic materials including non-collinear antiferromagnets, p-wave magnets and altermagnets, are an emerging frontier for quantum spintronics and hybrid quantum dev…
Navigating Chiral Spin Architectures in Non-Collinear Antiferromagnetic Thin Films
Freya Johnson, Jan Zemen, Geri Topore +6
Noncollinear antiferromagnets offer much promise for antiferromagnetic spintronics and neuromorphic applications with a plethora of functional properties surpassing many competing…
Large Nernst effect in Te-based van der Waals materials
M. Behnami, M. Gillig, A. G. Moghaddam +14
Layered van der Waals tellurides reveal topologically non-trivial properties that give rise to unconventional magneto-transport phenomena. Additionally, their semimetallic characte…
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…
The Impact of Local Strain Fields in Non-Collinear Antiferromagnetic Films
Freya Johnson, Frederic Rendell-Bhatti, Bryan D. Esser +5
Antiferromagnets hosting structural or magnetic order that breaks time reversal symmetry are of increasing interest for 'beyond von Neumann computing' applications because the topo…
Anomalous Nernst effect in MnNiN thin films
Sebastian Beckert, João Godinho, Freya Johnson +13
The observation of a sizable anomalous Hall effect in magnetic materials with vanishing magnetization has renewed interest in understanding and engineering this phenomenon. Antifer…
Unidirectional magnetoresistance and spin-orbit torque in NiMnSb
J. Železný, Z. Fang, K. Olejník +9
Spin-dependent transport phenomena due to relativistic spin-orbit coupling and broken space-inversion symmetry are often difficult to interpret microscopically, in particular when…
Multifunctional Antiperovskites driven by Strong Magnetostructural Coupling
Harish K. Singh, Ilias Samathrakis, Nuno M. Fortunato +4
Based on density functional theory calculations, we elucidated the origin of multifunctional properties for cubic antiperovskites with noncollinear magnetic ground states, which ca…
Effect of N, C and B interstitials on the structural and magnetic properties of alloys with CuAu-structure
Ingo Opahle, Harish K. Singh, Jan Zemen +2
High-throughput density functional calculations are used to investigate the effect of interstitial B, C and N atoms on 21 alloys reported to crystallize in the cubic CuAu struc…
The anomalous Hall effect in non-collinear antiferromagnetic MnNiN thin films
David Boldrin, Ilias Samathrakis, Jan Zemen +7
We have studied the anomalous Hall effect (AHE) in strained thin films of the frustrated antiferromagnet MnNiN. The AHE does not follow the conventional relationships with ma…
Multi-site exchange enhanced barocaloric response in MnNiN
David Boldrin, Eduardo Mendive-Tapia, Jan Zemen +9
We have studied the barocaloric effect (BCE) in the geometrically frustrated antiferromagnet MnNiN across the Néel transition temperature. Experimentally we find a larger bar…
Piezomagnetic effect as a counterpart of negative thermal expansion in magnetically frustrated Mn-based antiperovskite nitrides
Jan Zemen, Zsolt Gercsi, Karl G. Sandeman
Electric-field control of magnetization promises to substantially enhance the energy efficiency of device applications ranging from data storage to solid-state cooling. However, th…
