Nonequilibrium Kondo-vs.-RKKY scenarios in nanoclusters

Ydman, Simon LU ; Hopjan, Miroslav LU and Verdozzi, Claudio LU (2018) In EPL 123(4).
Abstract

Ultrafast manipulations of magnetic phases are eliciting increasing attention from the scientific community because potentially relevant to the understanding of nonequilibrium phase transitions and to novel technologies. Here, we focus on manipulations applied to magnetic impurities in metallic hosts. By considering small nanoring geometries, we show how currents can induce a dynamical switching between different types of exchange interactions in these systems. Our work thus opens a study window on nonequilibrium Doniach's magnetic phase diagrams, and time-dependent Kondo-vs.-RKKY scenarios.
