Material properties particularly suited to be measured with helium scattering: selected examples from 2D materials, van der Waals heterostructures, glassy materials, catalytic substrates, topological insulators and superconducting radio frequency materials
Holst, Bodil; Alexandrowicz, Gil; Avidor, Nadav; Benedek, Giorgio; Bracco, Gianangelo; Ernst, Wolfgang E.; Farias, Daniel; Jardine, Andrew P.; Lefmann, Kim; Manson, Joseph R.; Marquardt, Roberto; Artés, Salvador Miret; Sibener, Steven J.; Wells, Justin W; Tamtögl, Anton; Allison, William (Peer reviewed; Journal article, 2021)Helium Atom Scattering (HAS) and Helium Spin-Echo scattering (HeSE), together helium scattering, are well established, but non-commercial surface science techniques. They are characterised by the beam inertness and very ... -
Spin orientation in solid solution hematite-ilmenite
Brok, Erik; Frandsen, Cathrine; Lefmann, Kim; McEnroe, Suzanne; Robinson, Peter; Burton, Benjamin P; Hansen, Thomas C; Harrison, Richard (Journal article; Peer reviewed, 2017)The spin orientation in synthetic hematite-ilmenite samples and in a sample of natural hematite was studied from room temperature to above the antiferromagnetic-paramagnetic phase transition (the Néel temperature; TN ≈ ...
