Project Summary
 An interdisciplinary group of four physicists and four chemists have common research interests in molecular magnetism, new materials synthesis, and nanotechnology, and in several cases, formal interdisciplinary collaborations exist.  A variety of new magnetic systems and nanodevices are prepared, and they are presently characterized by magnetotransport, nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), atomic force microscopy (AFM), near-field microscopy (NFM), and other spectroscopies including infrared, ultraviolet/visible, and Raman.  Presently when macroscopic magnetic measurements are required, the specimens are studied with a Quantum Design MPMS 5 Tesla SQUID (superconducting quantum interference device) magnetometer.  This instrument is 10 years old, and its capability is over-subscribed, resulting in substantial waiting times before access to the instrument.  Consequently, we are proposing to acquire a modern version of this magnetometer, the Quantum Design MPMS 7 Tesla SQUID magnetometer.  The need for the new instrument reflects the significant rise in recent years of the number of researchers at the University of Florida with activities related to magnetic phenomena.  In addition, this new instrument will serve as an important interdisciplinary educational and training tool for graduate students and postdoctoral researchers who will operate the equipment.  Finally, the University of Florida has committed funding which represents 30% of the total cost of the instrument.
