Condensed-Matter Physics & Materials Science Seminar

"High pressure neutron Larmor diffraction measurements of ferromagnetic superconductor UGe2."

Presented by Dmitri Sokolov, Univ. of Edinburgh, United Kingdom

Monday, January 31, 2011, 1:00 pm — Small Seminar Room, Bldg. 510

Observation of an unconventional superconductivity in ferromagnetic UGe2 when ferromagnetism is suppressed by pressure indicates a dramatic modification of its electronic structure near the Quantum Critical Point [1]. I will present high resolution measurements of the lattice constants of UGe2 under pressure probed by a novel neutron scattering technique, which utilizes Larmor precession of polarized neutrons and surpasses the resolution of conventional scattering methods by an order of magnitude. I will also present our recent advances in single crystal growth of intermetallic compounds and development of the pressure cells for neutron scattering measurements.
