This site from the Georgia State University provides a good introduction to and illustration of the Meissner Effect, the property of a superconducting material whereby it actively excludes a magnetic field from within its interior.

Wikipedia.com offers a good introduction to diamagnetism and diamagnetic materials, including discussion of how superconductors exhibit diamagnetic properties.

Wikipedia.com offers a wonderful introduction and explanation of the Meissner effect, explaining how this effect qualifies superconduction as a true thermodynamic state of a material.

J. Georg Bednorz jointly revolutionized superconductivity research with K. Alex Muller by discovering an entirely new class of superconductors, often referred to as high-temperature superconductors. They managed to achieve...

Leon Cooper shared the 1972 Nobel Prize in Physics with John Bardeen and Robert Schrieffer, with whom he developed the first widely accepted theory of superconductivity. Termed the BCS theory, it is heavily based on a phenomenon known as...

Heike Kamerlingh Onnes was a Dutch physicist who first observed the phenomenon of superconductivity while carrying out pioneering work in the field of cryogenics. An important step on the way to this discovery was his success in...

In their search for new superconductors, Swiss theoretical physicist Karl Alexander Muller and his young colleague, J. Georg Bednorz, abandoned the metal alloys typically used in superconductivity research in favor of a class of oxides...

Walther Meissner discovered while working with Robert Ochsenfeld that superconductors expel relatively weak magnetic fields from their interior and are strongly diamagnetic. This phenomenon, commonly known as the Meissner effect or the...

This site from the Georgia State University provides a brief introduction to diamagnetism, explaining how Lenz's law accounts for diamagnetic behavior in all materials.
