  1. MRI: Acquisition of High Field Physical PropertiesMeasurement System with Cryogenic AFM/MFMP. Chris Hammel, Ohio State University, DMR 1040296 • This powerful instrument for characterization and imaging of nanoscale magnetic and spintronic systems was commissioned in March 2012 • Instrument located in the NanoSystems Laboratory (NSL), an OSU user facility • Equipment is available to a broad scientific community • Equipment is expertly maintained enabling excellent up-time • Instrument is providing data central to the OSU Center for Emergent Materials (NSF MRSEC) research program • Thermal response to applied heat pulse • Spatially resolved magnetic imaging of nanoscale magnetic dots confirms ferromagnetism Thermal spintronics : a) Thermal voltage Vth induced in (b) Pt/Ni/Pt junction by applied heat pulse measured by PPMS Magnetic nanoparticles: CryoMFM images of nanodots at two opposite polarities of magnetic probe characterizes their ferromagnetism a) b) heater Ni Pt Pt 200 nm 200 nm Data from K. Wickey and E. Johnston-Halperin

  2. MRI: Acquisition of High Field Physical PropertiesMeasurement System with Cryogenic AFM/MFMP. Chris Hammel, Ohio State University, DMR 1040296 • Installation of the Instrument in an established facility, NanoSystems Laboratory (NSL) enhanced and broadened impact • Since commissioning in March • 9 OSU research groups benefited from equipment • 19 users used the instruments • 4 female users among them • Instrument use continued to grow • Instrument capabilities contributed to the establishment of collaboration between OSU Center for Emergent Materials (NSF MRSEC) and Charles University (Prague, Czech Republic) • Funded by Czech Republic Fulbright grant: 15120812 “Spintronics - New Generation of Electronic Devices Using Spin-based Logic” Monthly PPMS use since installation Helena Reichlova, visiting Fulbright scholar from the Czech Republic, using our PPMS with CryoAFM for the study of novel spintronic devices
