Impact of synthesis method on the structure and function of high entropy oxides
Mario U. González-Rivas, Solveig S. Aamlid, Megan R. Rutherford +9
The term sample dependence describes the troublesome tendency of nominally equivalent samples to exhibit different physical properties. High entropy oxides (HEOs) are a class of ma…
Tetragonal BaCoO: A Co Ferromagnetic Mott Insulator with Inverted Spin Crossover
Mingyu Xu, Haozhe Wang, Krishna Prasad Koirala +13
The interplay between crystal electric field splitting of d states and Hund's rule exchange energy in cobalt-based perovskites offers a promising avenue for inducing spin-state tra…
Effect of high pressure synthesis conditions on the formation of high entropy oxides
Solveig Stubmo Aamlid, Minu Kim, Mario U. González-Rivas +3
High entropy materials are often entropy stabilized, meaning that the configurational entropy from multiple elements sharing a single lattice site stabilizes the structure. In this…
Short-range order and local distortions in entropy stabilized oxides
Solveig S. Aamlid, Sam Mugiraneza, Mario U. González-Rivas +3
An idealized high entropy oxide is characterized by perfect chemical disorder and perfect positional order. In this work, we investigate the extent to which short-range order (SRO)…
Physical properties and electronic structure of the two-gap superconductor VGa
P. -Y. Cheng, Mohamed Oudah, T. -L. Hung +16
We present a thorough investigation of the physical properties and superconductivity of the binary intermetallic V2Ga5. Electrical resistivity and specific heat measurements show t…
