  • Ferrimagnets possess multiple spin sub-lattices resulting in a complex magnon band structure and subtle spin transport across interfaces. Here, the authors show how the spin Seebeck effect, the thermal generation of pure spin current, may be an effective tool to study these magnetic excitations.

  • Interpretation of the physical phenomena observed in non-collinear antiferromagnets is challenging; imaging and writing magnetic domains is important for applications. Here the authors show magnetic domain imaging and writing in a non-collinear antiferromagnet by recording anomalous Nernst voltage in response to a localized thermal gradient.

  • Altermagnets, unlike their conventional collinear antiferromagnetic counterparts, allow for an anomalous Nernst response despite their collinear compensated magnetic ordering. Here, Badura et al find such an anomalous Nernst effect at zero magnetic field in the altermagnetic candidate, Mn5Si3.

  • Probing spin pumping in the terahertz regime allows one to reveal its initial elementary steps. Here, the authors show that the formation of the spin Seebeck current in YIG/Pt critically relies on hot thermalized metal electrons because they impinge on the metal-insulator interface with maximum noise.

  • The classification of magnets now includes altermagnets which possess opposite-spin sublattices connected by rotation and share some features with ferro- and antiferromagnets. Here the authors report the anomalous Hall effect in Mn5Si3 and interpret the results in terms of a d-wave altermagnetic phase.

  • Measurements of the spin Seebeck effect, the generation of spin current in a ferromagnet due to a temperature gradient, are often hindered by parasitic effects. Here, the authors use ferromagnetic insulators to show how transverse spin Seebeck measurements can be explained by the longitudinal spin Seebeck.

  • Electrical transport measurements reveal that Co3Sn2S2 is probably a magnetic Weyl semimetal, and hosts the highest simultaneous anomalous Hall conductivity and anomalous Hall angle. This is driven by the strong Berry curvature near the Weyl points.

  • The observation of the spin Nernst effect in platinum thin film is reported. This and the spin Hall effects are found to be of similar magnitude.

  • Topological spin textures are promising for their potential application in racetrack memory devices. Here, the characteristic Hall transport signature of antiskyrmions is investigated in Mn1.4PtSn, providing a platform for higher magnetic and temperature tunability over traditional skyrmion compounds.
