Switching Magnetism and Superconductivity with Spin-Polarized Current in Iron-Based Superconductor.
We explore a new mechanism for switching magnetism and superconductivity in a magnetically frustrated iron-based superconductor using spin-polarized scanning tunneling microscopy (SPSTM). Our SPSTM study on single-crystal Sr_{2}VO_{3}FeAs shows that a spin-polarized tunneling current can switch the Fe-layer magnetism into a nontrivial C_{4} (2×2) order, which cannot be achieved by thermal excit...
متن کاملExperimental 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 کاملSimultaneous optimization of spin fluctuations and superconductivity under pressure in an iron-based superconductor.
We present a high-pressure NMR study of the overdoped iron pnictide superconductor NaFe0.94Co0.06As. The low-energy antiferromagnetic spin fluctuations in the normal state, manifest as the Curie-Weiss upturn in the spin-lattice relaxation rate 1/(75)T1T, first increase strongly with pressure but fall again at P>Popt=2.2 GPa. Neither long-ranged magnetic order nor a structural phase transition ...

متن کاملCoexistence of Magnetism and Superconductivity in Separate Layers of Iron-Based Superconductor Li1−xFex(OH)Fe1−ySe
The magnetic properties attributed to the hydroxide layer of Li1−xFex(OH)Fe1−ySe have been elucidated by the study of superconducting and non-superconducting members of this family of compounds. Both a.c. magnetometry and muon spin relaxation measurements of non-superconductors find a magnetic state existing below ≈ 10 K which exhibits slow relaxation of magnetisation. This magnetic state is ac...
