The Discovery of Miassite
Miassite, a naturally occurring mineral, was first identified as a regular superconductor in 2010. However, recent research has revealed that it also exhibits unconventional superconductivity, making it the first naturally occurring mineral to demonstrate this property. The researchers used a combination of techniques, including X-ray diffraction, electron microscopy, and spectroscopy, to study the crystal structure and electronic properties of miassite.
