Large spontaneous magneto-thermoelectric effect in epitaxial thin films of the topological kagome ferromagnet Fe3Sn

Shun'ichiro Kurosawa, Tomoya Higo, Shota Saito, Ryota Uesugi, and Satoru Nakatsuji

Phys. Rev. Materials 8, 054206 (2024) - Published 28 May, 2024

This study investigates the anomalous Nernst effect (ANE), a novel technique to convert heat into electricity utilizing the magnetic and topological properties of materials. Unlike the Seebeck effect, ANE employs established thin-film technology to develop practical thermoelectric devices. We have successfully fabricated high-quality (0001)-oriented epitaxial films of the topological kagome ferromagnet Fe3Sn and characterized their thermoelectric properties. These films exhibit a large “zero-field” ANE signal of ~3 µV/K at room temperature due to large magneto-crystalline anisotropy as well as the shape anisotropy for in-plane magnetization arrangements, making them ideal for applications such as heat flux sensors and energy harvesters. This breakthrough in utilizing Fe3Sn films not only advances the understanding of ANE in topological magnets but also paves the way for the design of high-performance thermoelectric devices.

Fidelity and variability in the interlayer electronic structure of the kagome superconductor CsV3Sb5

Aurland K. Watkins, Dirk Johrendt, Vojtech Vlcek, Stephen D. Wilson, and Ram Seshadri

Phys. Rev. Materials 8, 054204 (2024) - Published 20 May, 2024

A reliable interlayer band structure of the kagome superconductor CsV3Sb5 is critical for understanding emergent phenomena like the charge density wave ordering and for classifying the topology. Here, the authors present a survey of computational techniques aimed at comparing the electronic interactions between kagome layers in CsV3Sb5. This study highlights the computational parameters and plotting methods that lead to differing band behaviors. Within conventional DFT, the parameters employed during structural relaxation are critical in determining the electronic structure between kagome layers. However, higher levels of computational theory contrast these results and point to the increased role of interlayer interactions.

Fermiology and transport properties of the candidate topological crystalline insulator SrAg4Sb2

J. Green, Eve Emmanouilidou, Harry W. T. Morgan, William T. Laderer, Chaowei Hu, Jonathan Loera, Anastassia N. Alexandrova, and Ni Ni

Phys. Rev. Materials 8, 054205 (2024) - Published 23 May, 2024

Inspired by the nonmagnetic topological materials database, the authors investigated the 3D fermiology and band topology of the Topological Crystalline Insulator (TCI) candidate SrAg4Sb2. The fermiology, revealed by angular-dependent quantum oscillations, shows excellent agreement with first-principles calculations. Symmetry and topology analysis result in two potential sets of topological invariants, suggesting the emergence of crystal-symmetry-protected gapless Dirac surface states either on the as-grown ab planes or on both the ab planes and as-grown mirror planes. Their findings provide evidence that SrAg4Sb2 is a promising TCI for exploring topological surface states protected by crystal symmetry.
