Abstract

Recent advances in superconducting VLSI technology have led to the development of miniature SQUID gradiometers and suscep-tometers configured for the detection of small magnetic fields with nearly quantum-limited sensitivity. These devices have proven to be valuable tools in the study of both local and global magnetic behavior in diluted magnetic semiconductors, providing the fine sensitivity necessary to explore the properties of thin films and superlattice struc-tures. Furthermore, In combination with an ultrafast pulsed laser sys-tem, measurements can be made at picosecond time scales, providing a new understanding of the dynamics of the magnetic phenomena in these materials and th e effects of quantum confinement on magnetic behavior. © 1989 IEEE
