This makes them highly relevant in modern electronics and spintronics.

What is Superconductivity?

Superconductivity refers to a state where a material can conduct electricity with zero resistance.

In simple terms:

No energy is lost as heat
Electricity flows perfectly
Efficiency is maximized

Key Features of Superconductors

Occur at very low temperatures
Involve Cooper pair formation
Used in advanced technologies like MRI and maglev trains
