The measurement temperatures were (a), 30 K, (b), 25 K, (c), 20 K, and (d), 15 K. Angles of θ = 90° and 180° correspond to H||c and ||ab, respectively. Angle dependence of Jc normalized by Jc for H||ab (Jcab) measured at (e) 4 T, (f) 10 T, and (g) 16 T. The dashed lines are located at θ = 94° to clearly see the Jc peaks.
