Abstract ▼ AI-Helper

We have investigated the effect of $Y_2O_3$ nanoparticles on the pinning properties of $Y_2O_3$-doped $GdBa_2Cu_3O_{7-{\delta}}$ (GdBCO) films. Both undoped and $Y_2O_3$-doped GdBCO films were grown on $CeO_2$-buffered MgO (100) single crystal substrates by pulsed laser deposition (PLD) using KrF (${\lambda}=248nm$) laser. The $Y_2O_3$ doping contents were controlled up to ~ 2.5 area% by varying the internal angles of $Y_2O_3$ sectors put on the top surface of GdBCO target. Compared with the $Gd_2O_3$-doped GdBCO films previously reported by our group [1], the $Y_2O_3$-doped GdBCO films exhibited less severe critical temperature ($T_c$) drop and thus slightly enhanced critical current densities ($J_c$) and pinning force densities ($F_p$) at 65 K for the applied field parallel to the c-axis of the GdBCO matrix (B//c) with increasing the doping content. Below 40 K, the in-field $J_c$ and $F_p$ values of all $Y_2O_3$-doped GdBCO films exhibited higher than those of undoped GdBCO film, suggesting that $Y_2O_3$ inclusions might act as effective pinning centers.

The structural characteristics of samples were analyzed with an X-ray diffractometer (Bruker D8-Advance, Cu Kα radiation).
ion sites. Therefore, in this study, we selected Y₂O₃ as the dopant to prevent the serious T_c drop and thus to improve the in-field J_c values at relatively high temperatures. Here, we report the effect of the Y₂O₃ doping content on the T_c variation and the pinning properties of Y₂O₃-doped GdBCO films.

이론/모형

The zero-resistivity critical temperature (T_c,_zero) and normal state resistivity were measured by using a standard four-point probe technique. The magnetic hysteresis curves of samples were measured by a SQUID magnetometer (Quantum Design, MPMS XL-5). Magnetic J_c values were calculated from the M-H curves by using an extended Bean’s critical state model [25], where ∆M is the hysteresis loop width, a and b (a < b) are width and length of the rectangular films, respectively.
