(a) Resistivity versus temperature characteristics at different applied magnetic fields, where the magnetic field is parallel to the CNT growth direction, (b) irreversibility field and upper critical field as a function of temperature obtained from those curves, where the irreversibility field Hirr is defined as the field at which the ρ/ρN=3% and the upper critical field as the field at which the ρ/ρN=80%.
