Summary

Theorists in China and the US have discovered that altermagnets can transfer their unusual magnetic properties to nonmagnetic materials placed adjacent to them, a phenomenon called the "altermagnetic proximity effect." This effect allows nonmagnetic materials to acquire altermagnetic spin textures, potentially enabling new spintronic applications and devices. The research models semiconductor/altermagnet bilayer structures to demonstrate this effect.

Altermagnets can transfer their unusual magnetic properties to nonmagnetic materials placed next to them, say theorists in China and the US.

This so-called 'proximity effect' appears in models of semiconductor/altermagnet bilayer structures.

Like a chameleon adapting its colours, a nonmagnetic material aligns its spin-density pattern with a neighbouring altermagnet, acquiring altermagnetic spin textures via the altermagnetic proximity effect.
