Machine Learning Guided Discovery of Corundum High Entropy Oxides
Abraham A. Mancilla, Oliver A. Dicks, Solveig S. Aamlid +5
Early thinking in the field of high entropy oxides (HEOs) emphasized their likely abundance, with combinatorial arguments hinting at a myriad of new materials. The experimental rea…
Disentangling the contributions of individual cations to magnetic order in a spinel high entropy oxide
Mario Ulises González-Rivas, Chun-Fu Chang, Martin Bluschke +8
High entropy oxides (HEOs) can possess long-range ordered magnetic states despite their extreme chemical disorder. Very little is known about how the different chemical constituent…
Coherent high-velocity chiral magnons in the metallic altermagnet CrSb
Ashutosh K. Singh, Niclas Heinsdorf, Abraham A. Mancilla +8
We report the collective magnetism of the metallic altermagnet CrSb. Magnetic susceptibility and polarized neutron diffraction measurements show that CrSb is a perfectly compensate…
Direct Fabrication of a Superconducting Two-Dimensional Electron Gas on KTaO3(111) via Mg-Induced Surface Reduction
Chun Sum Brian Pang, Bruce A. Davidson, Fengmiao Li +16
Two-dimensional electron gases (2DEGs) at the surfaces of KTaO3 have become an exciting platform for exploring strong spin-orbit coupling, Rashba physics, and low-carrier-density s…
KCo(TeO) 2.5 HO : A mineral-inspired pseudo-honeycomb cobalt dimer antiferromagnet
Austin M. Ferrenti, Maxime A. Siegler, Yiqing Hao +9
In recent years, magnetically-frustrated triangular and honeycomb lattice cobaltates have seen extensive study in the pursuit of a quantum spin liquid (QSL) state in a real materia…
Vanishing ordered moment in the frustrated triangular lattice antiferromagnet CuNdO
Jonathan Gaudet, Dalmau Reig-i-Plessis, Bogeng Wen +9
We investigate the magnetic ground state of CuNdO, which is a delafossite with a triangular lattice of magnetic Nd ions that are well separated by non-magnetic Cu spacer…
