The charge distribution in R Fe AsO 1-x F x (R= La, Sm) iron pnictides is probed using As
nuclear quadrupole resonance. Whereas undoped and optimally doped or overdoped …

We present an all-electron, four-component relativistic implementation of electric field
gradients (EFGs) at the nuclei using Gaussian-type orbitals and periodic boundary …

A combination of synchrotron x-ray, neutron powder-diffraction, magnetization, heat-
capacity, and electrical-resistivity measurements reveals that NdMnAsO is an …

The phase diagram of NdFe 1− x Co x AsO for low cobalt substitution consists of a
superconducting dome (0.05< x< 0.20) with a maximum critical temperature of 16.5 (2) K for …

We present a detailed study of A 75 s nuclear magnetic resonance Knight shift and spin-
lattice relaxation rate in the normal state of stoichiometric polycrystalline LiFeAs. Our …

The superconducting critical temperature, T c, of FeSe can be dramatically enhanced by
intercalation of a molecular spacer layer. Here we report on a Se 77, Li 7, and H 1 nuclear …

We report an easy single step synthesis route of title compound NdFeAsO 0.80 F 0.20
superconductor having bulk superconductivity below 50 K. The title compound is …

A combination of x-ray diffraction, magnetization, and As 75 nuclear magnetic resonance
(NMR) experiments were performed on single-crystal EuFe 1. 9 Co 0. 1 As 2. The strength of …

F 19 NMR measurements in SmFeAsO 1− x F x, for 0.15≤ x≤ 0.2, are presented. The
nuclear spin-lattice relaxation rate 1/T 1 increases upon cooling with a trend analogous to …

MnFe (P, Ge) is a promising magnetocaloric material for potential refrigeration applications
near room temperature. However, its relatively large hysteresis and large temperature/field …
