Fig. 3 — a Magnetic field dependence of c-axis resistivity measured with different angles between field and the a-axis at T = 2 K. b Angular dependent upper critical field and zero-resistance field (μ₀H₀) by using different criterions of c-axis resistivity. c Field dependence of the c-axis-resistivity difference between θ = 0° and 90°. The resistivity difference changes its sign at a field of about 2.4 T.
