n-value as a function of Jc in the 30-4.2 K temperature range.
Magnetic field was applied up to 16 T in the 30-10 K temperature range and in high-field up to 35 T at 4.2 K. The black lines are linear eye-guides and the red arrows emphasize the trend followed by the data approaching the ab-direction.
