Figure 5: Anisotropic properties of the upper critical magnetic field tested for another CNT–NbC composite.
From: Highly aligned carbon nanotube forests coated by superconducting NbC

The inset shows the angular dependence of the Tc2 (the temperature at which ρ/ρN=80%) at an applied field of 3 T, where 0° and 90° correspond to the field parallel and normal to the CNT growth direction, respectively.
