Abstract
This paper reviews our study on in-field superconducting properties and thermally activated vortex motion (creep) in BaFe2(As1-xPx)2 (Ba122:P) thin films with BaZrO3 nanoparticles fabricated on a MgO single crystal using pulsed laser deposition (PLD). We demonstrated that introducing controlled uniformly dispersed BaZrO3 nanoparticles into Ba122:P films significantly improves its in-field superconducting properties without degrading crystallinity, critical temperature and self-field critical current density (Jc). The nanoparticles doped Ba122:P films show an increase in Jc at all magnetic-field orientations and significantly reduced vortex creep, indicating that nanocomposite films could be a promising candidate for in-field applications.
