Quantum and thermal spin relaxation in diluted spin ice: Dy(2-x)MxTi2O7 (M = Lu, Y)
J. Snyder, B. G. Ueland, Ari Mizel +4
We have studied the low temperature a.c. magnetic susceptibility of the diluted spin ice compound Dy(2-x)MxTi2O7, where the magnetic Dy ions on the frustrated pyrochlore lattice ha…
Low Temperature Spin Freezing in Dy2Ti2O7 Spin Ice
J. Snyder, B. G. Ueland, J. S. Slusky +3
We report a study of the low temperature bulk magnetic properties of the spin ice compound Dy2Ti2O7 with particular attention to the (T < 4 K) spin freezing transition. While this…
Quantum-Classical Reentrant Relaxation Crossover in Dy2Ti2O7 Spin-Ice
J. Snyder, B. G. Ueland, J. S. Slusky +4
We have studied spin relaxation in the spin ice compound Dy2Ti2O7 through measurements of the a.c. magnetic susceptibility. While the characteristic spin relaxation time is thermal…
MgB2 Energy Gap Determination by Scanning Tunneling Spectroscopy
T. W. Heitmann, S. D. Bu, D. M. Kim +13
We report scanning tunneling spectroscopy (STS) measurements of the gap properties of both ceramic MgB2 and c-axis oriented epitaxial MgB2 thin films. Both show a temperature depen…
Dirty Spin Ice: The Effect of Dilution on Spin Freezing in Dy2Ti2O7
J. Snyder, J. S. Slusky, R. J. Cava +1
We have studied spin freezing in the diluted spin ice compound Dy2-xYxTi2O7 where the non-magnetic Y ions replace the magnetic Dy ions on the frustrated pyrochlore lattice. Magneti…
Giant anharmonicity and non-linear electron-phonon coupling in MgB; A combined first-principles calculations and neutron scattering study
T. Yildirim, O. Gulseren, J. W. Lynn +12
We report first-principles calculations of the electronic band structure and lattice dynamics for the new superconductor MgB. The excellent agreement between theory and our i…
