Floating zone growth at high oxygen pressures in Ruddlesden-Popper bilayer nickelate YSrNiAlO
H. Yilmaz, P. Sosa-Lizama, M. Knauft +7
With the discovery of superconductivity under pressure in the Ruddlesden-Popper (RP) bilayer LaNiO and trilayer LaNiO, a new field of nick…
Unveiling the Interfacial Reconstruction Mechanism Enabling Stable Growth of the Delafossite PdCoO2 on Al2O3 and LaAlO3
Anna Scheid, Tobias Heil, Y. Eren Suyolcu +7
Delafossites, comprised of noble metal (A+) and strongly correlated sublayers (BO2-), form natural superlattices with highly anisotropic properties. These properties hold significa…
Magnetotransport Properties in Epitaxial Films of Metallic Delafossite PdCoO: Effects of Thickness and Width Variations in Hall Bar Devices
Arnaud P. Nono Tchiomo, Anand Sharma, Sethulakshmi Sajeev +4
We report on a combined structural and magnetotransport study of Hall bar devices of various lateral dimensions patterned side-by-side on epitaxial PdCoO thin films. We study t…
Nonlinear optical response and spontaneous polarization in layer-stacked gallenene using second harmonic generation
Muhammad Yunusa, Andrew K. Schulz, Tim Parker +12
Gallenene is a promising low-dimensional material with a structure down to the thickness of a single atom, similar to graphene. However, van der Waals stacking of two-dimensional (…
Imaging atomic-scale magnetism with energy-filtered differential phase contrast method
Devendra Singh Negi, Peter A. van Aken, Jan Rusz
We propose differential phase contrast (DPC) imaging using energy-filtered electrons to image the magnetic properties of materials at the atomic scale. Compared to DPC measurements…
Adsorption-controlled Growth of Homoepitaxial c-plane Sapphire Films
Lena N. Majer, Tolga Acartürk, Peter A. van Aken +13
Sapphire is a technologically highly relevant material, but it poses many challenges to performing epitaxial thin-film deposition. We have identified and applied the conditions for…
