| Doping-induced contribution to the millikelvin magnetic susceptibility of Cd0.95Mn0.05Se:In has been found to undergo a maximum at n ≈ 2nc, and to vanish for n ≥ 8nc, where nc is the electron concentration corresponding to the metal-insulator transition. This confirms the presence, also in the metallic phase, of bound magnetic polarons. Their slow dynamics may account for hysteresis visible in our magnetoresistance data. |
