Abstract

In order to improve superconducting properties of REBCO films under magnetic fields, we fabricated BHO-doped SmBCO films on IBAD-MgO substrates by PLD method using alternating-targets technique which can change the content of the BHO in the SmBCO films. Consequently, Tcs and Jcs at self-field of the BHO-doped SmBCO films were decreased from 92 K to 89 K and 3.0 MA/cm2 to 1.2 MA/cm2 at 77 K in self-field with increasing the BHO content. However, Jc of the BHO-doped SmBCO films in high magnetic fields exceeded that of a pure-SmBCO film.
