Temperature and Magnetic Field Dependence of Spin Ice Correlations in the Pyrochlore Magnet Tb2Ti2O7
K. Fritsch, E. Kermarrec, K. A. Ross +6
We present a parametric study of the diffuse magnetic scattering at (1/2,1/2,1/2) positions in reciprocal space, ascribed to a frozen antiferromagnetic spin ice state in single cry…
Carrier localization and electronic phase separation in a doped spin-orbit driven Mott phase in Sr3(Ir1-xRux)2O7
Chetan Dhital, Tom Hogan, Wenwen Zhou +13
Interest in many strongly spin-orbit coupled 5d-transition metal oxide insulators stems from mapping their electronic structures to a J=1/2 Mott phase. One of the hopes is to estab…
The magnetic and structural properties near the Lifshitz point in Fe1+xTe
E. E. Rodriguez, D. A. Sokolov, C. Stock +5
We construct a phase diagram of the parent compound Fe1+xTe as a function of interstitial iron x in terms of the electronic, structural, and magnetic properties. For a concentratio…
Nonconventional Spin Glass Transition in a Chemically Ordered Pyrochlore
D. K. Singh, Y. S. Lee
We report on the study of unusual spin glass properties in the geometrically frustrated pyrochlore TbMoO, 24 K. The analysis of the nonlinear par…
Interplay of spin gap and nanoscopic quantum fluctuations in intermetallic CeCu2Ge2
D. K. Singh
Neutron scattering measurements are used to elucidate interplay of the field-induced spin gap and the quantum fluctuations in archetypal heavy electron system CeCuGe. A…
Molecular Quantum Magnetism in LiZn2Mo3O8
M. Mourigal, W. T. Fuhrman, J. P. Sheckelton +5
Inelastic neutron scattering for temperatures below 30 K from a powder of LiZn2Mo3O8 demonstrates this triangular-lattice antiferromagnet hosts collective magnetic excitations from…
