Superconductors allow electricity to pass through without any resistance, providing interesting phenomena such as quantum locking, as seen by the floating cube "locked" in space above a supercooled superconductor.

A team led by University of Minnesota Twin Cities researchers has discovered how subtle structural changes in strontium titanate, a metal oxide semiconductor, can alter the material's electrical resistance and affect its superconducting properties.

An oxide of strontium and titanium, strontium titanate or fabulite, has been on the radar of scientists for the past 60 years, mostly because it dis...
