Intertwined magnetic, structural, and electronic transitions in VO
Benjamin A. Frandsen, Yoav Kalcheim, Ilya Valmianski +15
We present a coordinated study of the paramagnetic-to-antiferromagnetic, rhombohedral-to-monoclinic, and metal-to-insulator transitions in thin-film specimens of the classic Mott i…
Probing the quantum phase transition in Mott insulator BaCoS_2 tuned by pressure and Ni-substitution
Z. Guguchia, B. A. Frandsen, D. Santos-Cottin +15
We present a muon spin relaxation study of the Mott transition in BaCoS_2 using two independent control parameters: (i) pressure p to tune the electronic bandwidth and (ii) Ni-subs…
Volume-wise destruction of the antiferromagnetic Mott insulating state through quantum tuning
Benjamin A. Frandsen, Lian Liu, Sky C. Cheung +25
Metal-to-insulator transitions (MITs) are a dramatic manifestation of strong electron correlations in solids1. The insulating phase can often be suppressed by quantum tuning, i.e.…
Antiferromagnetism and Hidden Order in Isoelectronic Doping of URuSi
M. N. Wilson, T. J. Williams, Y. -P. Cai +8
We present muon spin rotation (SR) and susceptibility measurements on single crystals of isoelectronically doped URuTSi (T = Fe, Os) for doping levels up to 50\%…
Long-Range Magnetic Order in the 5d^2 Double Perovskite Ba2CaOsO6: Comparison with Spin-Disordered Ba2YReO6
C. M. Thompson, J. P. Carlo, R. Flacau +11
The B-site ordered double perovskite Ba2CaOsO6 was studied by d.c. magnetic susceptibility, powder neutron diffraction and muon spin relaxation methods. The lattice parameter is a…
