Abstract:
A magnetic device usable in electronic devices is described. The magnetic device includes a magnetic junction and at least one smart thermal barrier that is thermally coupled with the magnetic junction. The magnetic junction includes at least one reference layer, at least one nonmagnetic spacer layer and a free layer. The nonmagnetic spacer layer(s) are between the reference layer(s) and the free layer. The free layer is switchable between stable magnetic states when a write current passed through the magnetic junction. The smart thermal barrier has a low heat conductance below a transition temperature range, and a high heat conductance above the transition temperature range.
