Magnetic Flux Quantisation
• Magnetic flux enclosed in a superconducting ring = integral multiples of fluxon• Φ = nh/2e = n Φ0 ( Φ0= 2 x 10-15 Wb)
Effect of Pressure
• Pressure ↑ => TC ↑• High TC superconductors – High pressure
Thermal Properties
• Entropy & Specific heat ↓ at TC
• Disappearance of thermo electric effect at TC
• Thermal conductivity ↓ at TC – Type I superconductors
