Exploring the Anomalous Nernst Effect in SrRuO
Anna Merin Francis, Avirup De, Abhijit Biswas +3
We investigate the anomalous Nernst effect in epitaxial SrRuO thin films grown on c-cut AlO substrates, and in a polycrystalline SrRuO slab. Through comprehensive m…
Tuneable electron-magnon coupling of ferromagnetic surface states in PdCoO
Federico Mazzola, Chi-Ming Yim, Veronika Sunko +11
Controlling spin wave excitations in magnetic materials underpins the burgeoning field of magnonics. Yet, little is known about how magnons interact with the conduction electrons o…
Magnetic frustration and spontaneous rotational symmetry breaking in PdCrO2
Dan Sun, Dmitry Sokolov, Jack Bartlett +8
In the triangular layered magnet PdCrO2 the intralayer magnetic interactions are strong, however the lattice structure frustrates interlayer interactions. In spite of this, long-ra…
Giant negative magnetoresistance and kinetic arrest of first-order ferrimagnetic-antiferomagnetic transition in Ge doped MnSb
Vikram Singh, R Rawat, Pallavi Kushwaha
Effect of Ge substitution on first order ferrimagnetic (FRI) - antiferromagnetic (AFM) transition in MnSb has been studied. It shows that transition temperature (T) can be…
Probing spin correlations using angle resolved photoemission in a coupled metallic/Mott insulator system
V. Sunko, F. Mazzola, S. Kitamura +16
A nearly free electron metal and a Mott insulating state can be thought of as opposite ends of possibilities for the motion of electrons in a solid. In the magnetic oxide metal PdC…
Itinerant ferromagnetism of the Pd-terminated polar surface of PdCoO
F. Mazzola, V. Sunko, S. Khim +9
We study the electronic structure of the Pd-terminated surface of the non-magnetic delafossite oxide metal PdCoO. Combining angle-resolved photoemission spectroscopy and densit…
Maximal Rashba-like spin splitting via kinetic energy-driven inversion symmetry breaking
Veronika Sunko, H. Rosner, P. Kushwaha +13
Engineering and enhancing inversion symmetry breaking in solids is a major goal in condensed matter physics and materials science, as a route to advancing new physics and applicati…
Nearly-free electrons in a 5d delafossite oxide metal
Pallavi Kushwaha, Veronika Sunko, P. J. W. Moll +11
Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is key to the realisation of numerous exotic phases including spin-orbit assisted Mott…
Evidence for hydrodynamic electron flow in PdCoO
Philip J. W. Moll, Pallavi Kushwaha, Nabhanila Nandi +2
Electron transport is conventionally determined by the momentum-relaxing scattering of electrons by the host solid and its excitations. The electrical resistance is set by geometri…
Quantum Oscillations and Magnetic Reconstruction in the Delafossite PdCrO
Clifford W. Hicks, Alexandra S. Gibbs, Lishan Zhao +7
We report quantum oscillation data on the metallic triangular antiferromagnet PdCrO. We find that, to very high accuracy, the observed frequencies of PdCrO can be reproduce…
Crystal growth, resistivity and Hall effect of the delafossite metal PtCoO
Pallavi Kushwaha, Philip J. W. Moll, Nabhanila Nandi +1
We report single crystal growth of the delafossite oxide PtCoO, and basic transport measurements on single crystals etched to well-defined geometries using focused ion beam tec…
