EMR Measurements of Field-Induced Superconductor lamda-(BETS)2FexGa1-xCl4
Y. Oshima, E. Jobiliong, J. S. Brooks +6
We have performed high-field Electron Magnetic Resonance (EMR) measurements of lamda-(BETS)2FexGa1-xCl4 to clarify the role of Pi- and d-electrons in the paramagnetic (PM) and fiel…
Dielectric Relaxation in Nanopillar NiFe-Silicon Structures in High Magnetic Fields
R. Vasic, J. S. Brooks, E. Jobiliong +3
We explore the dielectric relaxation properties of NiFe nanowires in a nanoporous silicon template. Dielectric data of the NiFe-silicon structure show a strong relaxation resonance…
Magnetic, electronic and Shubnikov-de Haas investigation of the dense Kondo system CeAgSb2
E. Jobiliong, J. S. Brooks, E. S. Choi +2
Of the dense Kondo materials in the class CeTSb2 (where T = Au, Ag, Ni, Cu, or Pd), CeAgSb2 is special due to its complex magnetic ground state, which exhibits both ferro- and anti…
Semiconductive and Photoconductive Properties of the Single Molecule Magnets Mn12-Acetate and Fe8Br8
J. M. North, D. Zipse, N. S. Dalal +4
Resistivity measurements are reported for single crystals of Mn12-Acetate and Fe8Br8. Both materials exhibit a semiconductor-like, thermally activated behavior over the 200-300 K r…
Magneto-optical probe of antiferromagnetic sub-phases in a pi- d electronic system
I. Rutel, S. Okubo, H. Ohta +3
The highly insulating antiferromagnetic phase of the magnetic- organic conductor lambda-(BETS)2FeCl4 has been probed by resonant mm wave methods vs. magnetic field, temperature, an…
Disorder-driven magnetic field-dependent phases in an organic conductor
K. Storr, D. Graf, J. S. Brooks +3
We report inter-plane () electrical transport measurements in the \tp series of organic conductors at very high magnetic fields. In the field range between 36 and 60 T $R_{…
