Title

Localized high-energy magnetic excitations in a new dilute magnetic semiconductor

Abstract

A recently discovered dilute magnetic semiconductor Ba1-xKx(Zn1-yMny)2As2 represents a model system with decoupled spin and charge doping. This material can be accurately described by the density functional theory, resulting in specific theoretical predictions as to the doping-dependent energies of exchange interactions. Here we propose to verify these predictions experimentally on powder samples of Ba1-xKx(Zn1-yMny)2As2 using the IN8 spectrometer.
