متن کاملPressure-induced metal-insulator and spin-state transition in low-valence layered nickelates
Ab initio calculations predict a metal-insulator transition at zero temperature to occur in La4Ni3O8 at moderate pressures as a result of a pressure-induced spin-state transition. The spin-state transition that is seen at 105 K at ambient pressure, from a low-temperature high-spin state to a high-temperature low-spin state, has been observed to be shifted to lower temperatures as pressure is ap...
متن کاملPressure-induced spin-state transition of iron in magnesiowüstite (Fe,Mg)O
We present a detailed theoretical study of the electronic, magnetic, and structural properties of magnesiowüstite Fe1−xMgxO with x in the range between 0 and 0.875 using a fully charge self-consistent implementation of the density functional theory plus dynamical mean-field theory method. In particular, we compute the electronic structure and phase stability of the rocksalt B1-structured (Fe,Mg...
متن کاملPressure-induced quantum phase transition in the spin-liquid TlCuCl3.
The condensation of magnetic quasiparticles into the nonmagnetic ground state has been used to explain novel magnetic ordering phenomena observed in quantum spin systems. We present neutron scattering results across the pressure-induced quantum phase transition and for the novel ordered phase of the magnetic insulator TlCuCl3, which are consistent with the theoretically predicted two degenerate...
متن کاملPressure-induced inhomogeneous chiral-spin ground state in FeGe.
(57)Fe nuclear forward scattering on the chiral magnet FeGe reveals an extremely large precursor phase region above the helimagnetic ordering temperature T(C)(p) and beyond the pressure-induced quantum phase transition at 19 GPa. The decrease of the magnetic hyperfine field ⟨B(hf)⟩ with pressure is accompanied by a large increase of the width of the distribution of ⟨B(hf)⟩, indicating a strong ...
