We studied the exchange interactions mediated by polarized itinerant carriers in diluted magnetic semiconductor (DMS) junction. In contrast to the ordinary Ruderman–Kittel–Kasuya–Yosida oscillations, the induced moment possesses an interesting spiral motion, accompanied by angular oscillations. The spiral motion remains robust in the entire T
