Unveiling unconventional magnetism at the surface of SrRuO
Rosalba Fittipaldi, Roman Hartmann, Maria Teresa Mercaldo +23
Materials with strongly correlated electrons exhibit physical properties that are often difficult to predict as they result from the interactions of large numbers of electrons comb…
Orbital-selective metal skin induced by alkali-metal-dosing Mott-insulating CaRuO
M. Horio, F. Forte, D. Sutter +21
Doped Mott insulators are the starting point for interesting physics such as high temperature superconductivity and quantum spin liquids. For multi-band Mott insulators, orbital se…
Pattern Formation by Electric-field Quench in Mott Crystal
Nicolas Gauquelin, Filomena Forte, Daen Jannis +10
The control of Mott phase is intertwined with the spatial reorganization of the electronic states. Out-of-equilibrium driving forces typically lead to electronic patterns that are…
Spin-orbit coupling induced Van Hove singularity in proximity to a Lifshitz transition in SrRuO
Carolina A. Marques, Philip A. E. Murgatroyd, Rosalba Fittipaldi +19
Van Hove singularities (VHss) in the vicinity of the Fermi energy often play a dramatic role in the physics of strongly correlated electron materials. The divergence of the density…
Two-carrier Magnetoresistance: Applications to CaRuO
Lakshmi Das, Yang Xu, Tian Shang +13
Ambipolar transport is a commonly occurring theme in semimetals and semiconductors. Here we present an analytical formulation of the conductivity for a two-band system. Electron an…
Universal size-dependent nonlinear charge transport in single crystals of the Mott insulator CaRuO
Guerino Avallone, Remko Fermin, Kaveh Lahabi +6
The surprisingly low current density required for inducing the insulator to metal transition has made CaRuO an attractive candidate material for developing Mott-based elect…

C. Cirillo, V. Granata, G. Avallone +4
A comprehensive study of the behavior of the Mott insulator Ca_2RuO_4 under electrical current drive is performed by combining two experimental probes: the macroscopic electrical t…
Orbitally selective breakdown of Fermi liquid quasiparticles in CaSrRuO
Denys Sutter, Minjae Kim, Christian Matt +16
We present a comprehensive angle-resolved photoemission spectroscopy study of CaSrRuO. Four distinct bands are revealed and along the Ru-O bond direction their…
Anomalous orbital moment in the ferromagnetic phase of the Sr4Ru3O10
Filomena Forte, Lucia Capogna, Veronica Granata +3
The coupling of spin and orbital degrees of freedom in the trilayer Sr4Ru3O10 sets a long-standing puzzle, due to the peculiar anisotropic coexistence of out-of-plane ferromagnetis…
Layer dependent antiferromagnetism in the Sr4Ru3O10 ruthenate at the metamagnetic-like transition
