It is essential to understand the flux pinning properties of an APC-doped REBCO film at low temperatures in order to achieve the high-performance superconducting applications. We fabricated 8.4 mol. % BHO-doped SmBa<sub>2</sub>Cu<sub>3</sub>O<sub>y</sub> (SmBCO) film on LaAlO<sub>3</sub> (LAO) substrates by pulsed laser deposition method and measured the superconducting properties at 77, 65, 40, and 20 K. As for the magnetic field dependence of <i>J</i><sub>c</sub>, the <i>J</i><sub>c</sub> of the BHO-doped SmBCO film was significantly higher than that of the pure SmBCO film at all temperatures. Furthermore, in the magnetic field angular dependence of <i>J</i><sub>c</sub>, the BHO-doped SmBCO film exhibited the peaks of <i>J</i><sub>c</sub> around <i>B</i>//<i>c</i> at 77, 65, and 40 K in 3 T. These results suggested that the flux pinning force of BHO nanorod was effective even at 65 and 40 K.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>barium compounds; flux pinning; high-temperature superconductors; nanorods; pulsed laser deposition; samarium compounds; superconducting thin films; superconducting transition temperature; APC-doped REBCO film; BHO nanorod; BaHfO<sub>3</sub> doped SmBa<sub>2</sub>Cu<sub>3</sub>Oy films; LaAlO<sub>3</sub>; LaAlO<sub>3</sub> substrates; SmBa<sub>2</sub>Cu<sub>3</sub>O<sub>y</sub>:BaHfO<sub>3</sub>; flux pinning properties; magnetic field angular dependence; magnetic flux density 3 T; pulsed laser deposition method; superconducting properties; temperature 20 K; temperature 40 K; temperature 65 K; temperature 77 K; Films; Flux pinning; Magnetic fields; Superconducting films; Temperature; Temperature measurement; <formula formulatype=$ $hbox{BaHfO}_{3}$; $hbox{SmBa}_{2}hbox{Cu}_{3}hbox{O}_{y}$ ; flux pinning; thin film;
