Briefing: Superconducting altermagnets could carry spin without energy loss

Researchers have proposed a new class of magnetic materials known as superconducting altermagnets, which could significantly improve the energy efficiency of superconductors by allowing for lossless transport of electron spins.

Published in Physical Review X, the study led by Kyle Monkman outlines calculations that suggest these materials could extend the zero-resistance currents characteristic of superconductors to include spin transport.

The implications of this research are substantial, with potential applications in advanced electronics and quantum computing, where efficient spin manipulation is crucial for performance.
