Magnetism, structure, and charge correlation at a pressure-induced Mott-Hubbard insulator-metal transition
Yejun Feng, R. Jaramillo, A. Banerjee +2
We use synchrotron x-ray diffraction and electrical transport under pressure to probe both the magnetism and the structure of single crystal NiS2 across its Mott-Hubbard transition…
Verwey transition in FeO at high pressure: quantum critical behavior at the onset of metallization
J. Spałek, A. Kozłowski, Z. Tarnawski +5
We provide evidence for the existence of a {\em quantum critical point} at the metallization of magnetite FeO at an applied pressure of GPa. We show t…
Structural dichroism in the antiferromagnetic insulating phase of VO
C. Meneghini, S. Di Matteo, C. Monesi +6
We performed near-edge x-ray absorption spectroscopy (XANES) at V K edge in the antiferromagnetic insulating (AFI) phase of a 2.8% Cr-doped VO single crystal. Linear dichro…
Magnetic correlations and quantum criticality in the insulating antiferromagnetic, insulating spin liquid, renormalized Fermi liquid, and metallic antiferromagnetic phases of the Mott system V_2O_3
Wei Bao, C. Broholm, G. Aeppli +6
Magnetic correlations in all four phases of pure and doped vanadium sesquioxide V_2O_3 have been examined by magnetic thermal neutron scattering. While the antiferromagnetic insula…
