Quantum spin effects may enhance one-way electrical transport in chiral magnets

Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, researchers from Science Tokyo report. In chiral magnetic systems, electric current flows differently depending on its direction, but the role of quantum effects in this behavior has remained unclear. Through theoretical analysis, the researchers showed that chiral magnetic systems exhibit logarithmic temperature dependence at low temperatures, offering new insights into electron transport in magnetic materials. These findings are expected to play a crucial role in spintronics.
