Search for Dimensional Effects in Spin-Glass Transition in Thin Cd<sub>1-x</sub>Mn<sub>x</sub>Te Multilayers
TL;DRAbstract
SQUID magnetic measurements of Cde/Cdx Mnx e, x c 0.5, multilayers with dicherent CdMnTe layer thickness w reveal the persistence of the spin-glass irreversibilitles down to _ 16 A thin layers, i.e. , well beyond the previously postulated 40 as a quasi-2D threshold. The freezing temperature Tf is found to be a monotonic function of w, and it obeys a scaling 1aw Tf CC w', with a 0.8 similar to tlat for canonical spin-glasses. Magnetic properties of all studied structures are found to be independent of the orientation of the magnetic field.
