Small-angle neutron scattering (SANS) is one of the most important techniques for
microstructure determination, being utilized in a wide range of scientific disciplines, such as …

Pinning force data, F p, of a variety of Fe-based high-T c superconductors (11-, 111-, 122-
and 1111-type) were analyzed by means of a scaling approach based on own experimental …

Magnetic skyrmions are promising candidates as information carriers in logic or storage
devices thanks to their robustness, guaranteed by the topological protection, and their …

In order to establish the doping dependence of the critical current properties in the iron-
based superconductors, the in-plane critical current density J c of BaF e 2 A s 2-based …

An extensive study of the magnetic properties of FeTe 0.7 Se 0.3 crystals in the
superconducting state is presented. We show that weak collective pinning, originating from …

We investigate the fishtail effect, critical current density (J c), and vortex dynamics in LiFeAs
single crystals. The sample exhibits a second peak (SP) in the magnetization loop only with …

We report superconducting (SC) properties of stoichiometric LiFeAs (T c= 17 K) studied by
small-angle neutron scattering (SANS) and angle-resolved photoemission (ARPES) …

By neutron scattering, we have observed a well-ordered magnetic vortex lattice (VL) in KFe
2 As 2 single crystals. With the field along the c axis, a nearly isotropic hexagonal VL is …

The occurrence of the second peak (SP) on the dc magnetization curves of iron pnictide and
chalcogenide single crystals (the'fishtail'effect) has been interpreted in surprisingly different …

We describe the technique of small-angle neutron scattering, as used to image the vortex
lattice in superconductors, and the information that can be gained from this technique. We …
