A rev iew on selected areas of researc h on low -di mensiona l str uctures consistin g of diluted magnetic (semimagnetic ) semiconductors is attem pted . I n the intro ductor y part , af ter short historica l prelimi nari es, w e descri be some early ideas and speculati ons concerning prop erties of such structures and w e conf ront them w ith real results obtained in the course of their exp erimental investigations. Several issues are addressed to but, in view of the richness of the Ùeld, the review is by no means not pretending to be an exhaustiv e one. W e begin w ith early studies of metal {insul ator{s emico ndu ctor structures and progress to structures grow n by molecula r b eam epitaxy . W e discuss, in particular, the idea of a spin sup erlattice, typ e-I-to-typ e-I I transition, wave functions mapping, and detailed determinati on of the proÙles of realisti c quantum w ells. W e put special emphasis on digital grow th and, speciÙcall y, parab oli c and half -parab oli c quantum w ells, use of tunable g -factor in studies of trions, self-assembled quantum dots, spin inj ection and, Ùnally, on hybrid structures of ferromagnets and diluted magnetic semiconductor structures.
