Antiferromagnetic fluctuations in the normal state of LiFeAs
P. Jeglic, A. Potocnik, M. Klanjsek +8
We present a detailed study of 75As NMR Knight shift and spin-lattice relaxation rate in the normal state of stoichiometric polycrystalline LiFeAs. Our analysis of the Korringa rel…
Electronic structure and magnetic properties of Li_2ZrCuO_4 - a spin 1/2 Heisenberg system in vicinity to a quantum critical point
M. Schmitt, J. Malek, S. -L. Drechsler +1
Based on density functional calculations, we present a detailed theoretical study of the electronic structure and the magnetic properties of the quasi-one dimensional chain cuprate…
Frustrated square lattice with spatial anisotropy: crystal structure and magnetic properties of PbZnVO(PO4)2
Alexander A. Tsirlin, Ramesh Nath, Artem M. Abakumov +3
Crystal structure and magnetic properties of the layered vanadium phosphate PbZnVO(PO4)2 are studied using x-ray powder diffraction, magnetization and specific heat measurements, a…
Uniform spin chain physics arising from NCN bridges in CuNCN: surprises on the way from copper oxides to their nitride analogs
Alexander A. Tsirlin, Helge Rosner
We report on the unexpected uniform spin chain physics in CuNCN, the insulating nitride analog of copper oxides. Based on full-potential band structure calculations, we derive the…
Highly Dispersive Spin Excitations in the Chain Cuprate Li2CuO2
W. E. A. Lorenz, R. O. Kuzian, S. -L. Drechsler +11
We present an inelastic neutron scattering investigation of Li2CuO2 detecting the long sought quasi-1D magnetic excitations with a large dispersion along the CuO2-chains studied up…
Influence of the Nd states on the magnetic behavior and the electric field gradient of the oxypnictides superconductors NdFeAsOF
P. Jeglic, J. -W. G. Bos, A. Zorko +5
The structural, electronic, and magnetic properties of the superconducting NdFeAsOF phases ( for ) have been investigated experimentally by hi…
