Abstract

A large magnetoresistance was observed in n-type Cdl-xMnxSe (x ≤ 0.10) at low temperatures. The concomitant changes in the Half coefficient as a function of H were also studied. These magnetotransport effects are caused by the s-d interaction. Some specific magnetoresistance mechanisms are discussed. The most likely dominant mechanisms are related to the giant spin splitting of the conduction band.
