Experimental aspects of Alpha, Beta angles distortion on superconductivity in 1111-type Iron-based superconductor
In this research, we aim to clarify the relationship between the structural distortion due to doping and the superconductivity existence in the FeAs4 structure. For this, we have prepared polycrystalline of NdFeAsO0.8F0.2, NdFeAs0.95Sb0.05O0.8F0.2 and Nd0.99Ca0.01FeAsO0.8F0.2 samples by one-step solid state reaction method. The structural and electrical properties of the samples were characteri...
متن کاملImaging the real space structure of the spin fluctuations in an iron-based superconductor
Spin fluctuations are a leading candidate for the pairing mechanism in high temperature superconductors, supported by the common appearance of a distinct resonance in the spin susceptibility across the cuprates, iron-based superconductors and many heavy fermion materials. The information we have about the spin resonance comes almost exclusively from neutron scattering. Here we demonstrate that ...
متن کاملConduction-electron spin resonance in the superconductor K3C60
The conduction-electron spin resonance of the superconducting fulleride compound, K3C60 (Tc519 K! has been observed between 2.5 and 800 K at several frequencies from 9 to 225 GHz. Between Tc and 0.7Tc the spin lifetime of normal excitations increases as predicted by the theory of Yafet for scattering from nonmagnetic structural defects. At lower temperatures the CESR arises from states bound to...
متن کاملMuon-spin rotation measurements of the magnetic penetration depth in the iron-based superconductor Ba1xRbxFe2As2
Measurements of the magnetic penetration depth � in the Fe-based superconductor Ba1−xRbxFe2As2 (x=0.3, 0.35, 0.4) were carried out using the muon-spin rotation (�SR) technique. The temperature dependence of � is well described by a two-gap s + s-wave scenario with a small gap Δ1 � 1–3 meV and a large gap Δ2�7–9 meV. By combining the present data with those previously obtained for RbFe2As2 a dec...
متن کاملPressure effect on iron-based superconductor LaFeAsO1−xHx: Peculiar response of 1111-type structure
A systematic study of the crystal structure of a layered iron oxypnictide LaFeAsO1-xHx as a function of pressure was performed using synchrotron X-ray diffraction. This compound exhibits a unique phase diagram of two superconducting phases and two parent phases. We established that the As-Fe-As angle of the FeAs4 tetrahedron widens on the application of pressure due to the interspace between th...
