Scanning magnetic and thermal imaging using Superconducting Quantum Interference Device (SQUID) fabricated on the apex of a sharp tip has attracted great attention because of its record magnetic sensitivity, thermal sensitivity and nanoscale spatial resolution. Many interesting phenomena like vortex dynamics in a superconductor, quantum hall state, and heat dissipation in graphene etc. has been investigated using scanning SQUID on tip microscopy. This is one of the most powerful tool for the investigation of a wide variety of quantum systems and novel materials.
