Identifying the octupole Antiferromagnetic domain orientation in MnNiN by scanning Anomalous Nernst Effect microscopy

F. Johnson, J. Kimák, J. Zemen +9

The intrinsic anomalous Nernst effect in a magnetic material is governed by the Berry curvature at the Fermi energy and can be realized in non-collinear antiferromagnets with vanis…

Ultrafast control of spin order by linearly polarized light in noncollinear antiferromagnetic metals

J. Kimak, M. Nerodilova, K. Carva +15

The non-thermal optical control of magnetic order offers a promising route to ultrafast, energy-efficient information technologies. Although optical manipulation of magnetism in me…

Disentangling magnetic and optical contributions in ultrafast dynamics of antiperovskite non-collinear antiferromagnets

J. Kimak, Tomas Ostatnicky, M. Nerodilova +14

Non-collinear antiferromagnets are a class of spin-polarized antiferromagnets in which chiral spin textures give rise to Berry-curvature-driven phenomena, such as the anomalous Hal…

Room temperature weak collinear ferrimagnet with symmetry driven, large intrinsic magneto-optic signatures

F. Johnson, J. Zázvorka, L. Beran +4

Here we present a magnetic thin film with a weak ferrimagnetic (FIM) phase above the Néel temperature ( = 240 K) and a non-collinear antiferromagnetic (AFM) phase below, ex…

Materials for Quantum Technologies: a Roadmap for Spin and Topology

N. Banerjee, C. Bell, C. Ciccarelli +22

In this Perspective article, we explore some of the promising spin and topology material platforms (e.g. spins in semi- and superconductors, skyrmionic, topological and 2D material…

Improvements to SDXL in NovelAI Diffusion V3

Juan Ossa, Eren Doğan, Alex Birch +1

In this technical report, we document the changes we made to SDXL in the process of training NovelAI Diffusion V3, our state of the art anime image generation model.
