The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

Investigation of vortex pinning and its relaxation is of great importance for both basic physics
and technological applications in the field of superconductivity. We report a great …

Plateletlike single crystals of the Ca (Fe 1-x Co x) 2 As 2 series having lateral dimensions up
to 15 mm and thicknesses up to 0.5 mm were obtained from the high-temperature solution …

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 …

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 …

The second magnetization peak (SMP) appears in most superconductors and is crucial for
the understanding of vortex physics as well as the application. Although it is well known that …

The importance of type-II superconductors with strong pinning comes from their ability to
carry large electrical currents in the presence of a magnetic field. We report on the results of …

In this work we present the results of the bulk magnetization measurements in a
superconducting state of single crystals of Ba 0.65 Na 0.35 Fe 2 As 2. The isothermal …

We have employed the high temperature solutions growth technique and the Bridgman
technique to grow cm-size high-quality single crystals of pristine BaFe2As2 (Ba122) and its …

Isothermal magnetic field dependence of magnetization and magnetic relaxation
measurements were performed for the $ H\parallel {\rm {c}} $ axis on a single crystal of Ba …
