N2 - To enhance Jc in high magnetic fields, we fabricated a SmBa 2Cu3Oy (SmBCO) film with a high number density (2830/μm2) of BaHfO3 (BHO) nanorods by pulsed laser deposition (PLD) adopting a low-temperature growth (LTG) technique (LTG-SmBCO + BHO). The LTG technique consists of seed layer deposition and subsequent film deposition at a lower temperature. The number density of BHO nanorods in the film was approximately 4 times higher than that in a BHO-doped SmBCO film fabricated by conventional PLD without a seed layer. The flux pinning performance of the LTG-SmBCO + BHO film (Fp = 23.8GN/m3 at 77K under 4.5 T) was comparable to the reported record high value of 28.3 GN/m3 at 77 K.
