The Takeaway
Electronic devices currently rely on separate components to store information and regulate electrical current. The material Mn3Si2Te6 breaks this mold by exhibiting both memristance and inductance as intrinsic properties of its crystal structure. These features emerge from the way electrons orbit within the crystal lattice rather than traditional charge movement. This allows the material to remember its previous state while also generating a magnetic response to current. Using a single material for multiple functions could lead to much smaller, more efficient computers. It paves the way for a new generation of integrated quantum circuits that are far simpler than current designs.
From the abstract
Orbital degrees of freedom offer a largely untapped route to emergent dynamical phenomena in correlated quantum materials. However, it remains unclear whether collective orbital states can intrinsically generate both reactive and memory functionalities in a bulk system. Here we show that in the ferrimagnet Mn3Si2Te6, nonequilibrium reconfiguration of chiral orbital currents produces both emergent inductance and nonvolatile memristance as intrinsic properties of a single crystal.
