摘要：

Magnetic properties of Cd1-yMnyS nanocrystals have been studied. They vary with the particle size and markedly differ from those observed in the bulk phase, in particular their interactions drastically increase compared to those observed in the latter case. A Mn2+-Mn2+ interaction enhancement with decreasing size involves changes in the magnetic phase diagram. For 4 nm nanocrystals, a spin glass phase can be assumed.
