A new planar DC SQUID with integrated pick-up loops and field coils has allowed detailed AC magnetic susceptibility measurements of Cd0.85Mn0.15Te/CdTe superlattices. Systematic dimensional studies show that reduced geometries can suppress the three-dimensional spin glass transition and produce nonequilibrium magnetic states. © 1987.
