Scientists in Japan have confirmed that ultra-thin films of ruthenium dioxide belong to a newly recognized and powerful class of magnetic materials called altermagnets. These materials combine the best of two magnetic worlds: they’re stable against interference yet still allow fast, electrical readout—an ideal mix for future memory technology.
The researchers also found that the performance of RuO2 thin films can be improved by carefully controlling how their crystal structure is oriented during fabrication. Their findings were published in Nature Communications.
