Coexistence of orbital and quantum critical magnetoresistance in FeSe(1-x)S(x)
The recent discovery of a non-magnetic nematic quantum critical point (QCP) in the iron chalcogenide family FeSe$_{1-x}$S$_{x}$ has raised the prospect of investigating, in isolation, the role ofExpand
Pressure induced static magnetic order in superconducting FeSe1-x.
A detailed investigation of the electronic phase diagram of FeSe1-x under pressures up to 1.4 GPa by means of ac magnetization and muon-spin rotation finds it to be one of the most interesting superconducting systems investigated extensively at present. Expand
Stripe quadrupole order in the nematic phase of FeSe$_{1-x}$S$_x$
We use polarization-resolved electronic Raman spectroscopy to study charge dynamics in non-magnetic FeSe$_{1-x}$S$_x$ superconductor. We observe two features of the $XY$ quadrupole symmetry: aExpand
Magnetic ground state of FeSe
Inelastic neutron-scattering experiments that reveal both stripe and Néel spin fluctuations over a wide energy range at 110 K suggest that FeSe is a novel S=1 nematic quantum-disordered paramagnet interpolating between the NÉel and stripe magnetic instabilities. Expand
Magnetic fluctuations under pressure on S-doped FeSe studied via 77Se NMR
FeSe1-xSx has attracted much attention among iron-based superconductors because the pure sample undergoes nematic and superconducting (SC) phase transitions without magnetism. A pressure-inducedExpand
NMR evidence for static local nematicity and its cooperative interplay with low-energy magnetic fluctuations in FeSe under pressure
We present $^{77}$Se-NMR measurements on single-crystalline FeSe under pressures up to 2 GPa. Based on the observation of the splitting and broadening of the NMR spectrum due to structural twinExpand
Pressure Induced Stripe-Order Antiferromagnetism and First-Order Phase Transition in FeSe.
A high-pressure NMR study on FeSe single crystals reveals the magnetic phase transition to be first-order type, implying the existence of a concomitant structural transition via a spin-lattice coupling and provides clear evidence for strong coupling between nematicity and magnetism in FeSe. Expand
Formation of a Nematic Fluid at High Fields in Sr3Ru2O7
It is reported that, in the close vicinity of a metamagnetic quantum critical point, high-purity strontium ruthenate Sr3Ru2O7 possesses a large magnetoresistive anisotropy, consistent with the existence of an electronic nematic fluid. Expand

An overview of nematicity, magnetism and superconductivity is presented, and the interplay of these phases in FeSe is discussed, focusing on bulk FeSe and the effects of physical pressure and chemical substitutions as tuning parameters. Expand
Pressure-induced antiferromagnetic transition and phase diagram in FeSe
We report measurements of resistance and ac magnetic susceptibility on FeSe single crystals under high pressure up to 27.2 kbar. The structural phase transition is quickly suppressed with pressure,Expand
