We report a Fe K x-ray emission spectroscopy study of local magnetic moments in various iron-based superconductors in their paramagnetic phases. Local magnetic moments are found in all samples studied: PrFeAsO, BaFe,Co 2 As 2, LiFeAs, Fe 1x Te,Se, and A 2 Fe 4 Se 5 where A=K, Rb, and Cs. The moment size is independent of temperature or. We use time-of-flight TOF inelastic neutron scattering INS spectroscopy to investigate the doping dependence of magnetic excitations across the phase diagram of NaFe1-xCoxAs with x = 0, 0.0175, 0.0215, 0.05, and 0.11. The effect of electron-doping by partially substituting Fe by Co is to form resonances that couple with superconductivity, broaden and suppress low energy E 80 meV spin. Here we report the interplay of magnetic and structural transitions in a parent compound of iron-based superconductor BaFe2As2 at high pressures, in which magnetic ordering precedes the structural transition at high pressures. Our results can be understood in terms of spin fluctuations in the emerging nematic phase before long-range magnetic order.

Strong electronic correlations are often associated with the proximity of a Mott-insulating state. In recent years however, it has become increasingly clear that the Hund#x27;s rule coupling intra-atomic exchange is responsible for strong correlations in multiorbital metallic materials that are not close to a Mott insulator. Hund#x27;s coupling has two effects: It influences the energetics of. The magnetic order of Nd was found in all samples, with a gradual increase of the polarized magnetic moment with decreasing temperature, saturating around 1 K. Hyperfine induced nuclear polarization of the Nd nuclear spin has been observed below about 400 mK for samples with x = 0, 0.13, 0.15 and 0.18.

Strong Correlations from Hund#x27;s Coupling.

Microscopic evidence shows that the parent compound BaFe 2 As 2 exhibits magnetic order SDW below 140 K which is accompanied by a structural phase transition. 15, 16 The situation is common to Sr. Effects of roughness on surface electronic and magnetic properties are studied here. Spin resolved density of states show the effect of roughness on the surface. For all concentration of roughness, magnetic moment of the surface layer is higher than its bulk value. Surface magnetic moment increases with increase in surface roughness.

What is/are Spin Freezing? Spin Freezing - The results show that the coercivity increased at lower measuring temperature due to spin freezing. [1] Together with the geometric frustration of the triangularly distributed Ce moments, this leads to a spin-glass phase below the spin freezing temperature Tf 0. [2] Similarly, for NiFe 2 O 4 SiO 2 sample, an unusual asymmetric hysteresis loop at. Magnetic materials are made up of very tiny magnets, which can be as small as individual electrons. The strength and direction of these are described by the magnetic moment. In quantum spin liquids, magnetic moments behave like a liquid and do not freeze or order even at absolute zero.
