Orbital disorder and ordering in NaTiSi2O6: 29Si and 23Na NMR Study
Ivo Heinmaa, Riho Rästa, Harlyn J. Silverstein +2
NaTiSi2O6 is an exemplary compound, showing an orbital assisted spin-Peierls phase transition at Tc = 210 K. We present the results of 29Si and 23Na NMR measurements of NaTiSi2O6.…
Spin Freezing in The Frustrated Disordered Quantum Magnet Ba(MnV)O
A. T. Hristov, M. C. Shapiro, Harlyn J. Silverstein +8
BaMnO is a geometrically frustrated spin dimer compound. We investigate the effect of site disorder on the zero field phase diagram of this material by considering the…
Statics and dynamics of the highly correlated spin ice Ho2Ge2O7
A. M. Hallas, J. A. M. Paddison, H. J. Silverstein +11
The pyrochlore Ho2Ge2O7 is a new highly correlated spin ice material. Physical property measurements including x-ray diffraction, dc susceptibility and ac susceptibility, confirm t…
Fermi surface evolution of Na-doped PbTe studied through density functional theory calculations and Shubnikov-de Haas measurements
P. Giraldo-Gallo, B. Sangiorgio, P. Walmsley +5
We present a combined experimental and theoretical study of the evolution of the low-temperature Fermi surface of lead telluride, PbTe, when holes are introduced through sodium sub…
Incommensurate crystal supercell and polarization-flop observed in the magnetoelectric ilmenite, MnTiO3
Harlyn J. Silverstein, Elizabeth Skoropata, Paul M. Sarte +6
MnTiO3 has been studied for many decades, but it was only in the last few years that its strong magnetoelectric behavior had been observed. Here, we use neutron scattering on two s…
Ground state selection in XY pyrochlore antiferromagnets RGeO (R = Er, Yb)
Z. L. Dun, X. Li, R. S. Freitas +9
Elastic neutron scattering, ac susceptibility, and specific heat experiments on the pyrochlores ErGeO and YbGeO show that both systems are antif…
Incipient Ferromagnetism in Tb2Ge2O7: Application of Chemical Pressure to the Enigmatic Spin Liquid, Tb2Ti2O7
A. M. Hallas, J. G. Cheng, A. M. Arevalo-Lopez +8
The origin of the spin liquid state in TbTiO has challenged experimentalists and theorists alike for nearly 20 years. To improve our understanding of the exotic magneti…
Liquid-like correlations in single crystalline Y2Mo2O7: an unconventional spin glass
H. J. Silverstein, K. Fritsch, F. Flicker +15
The spin glass behavior of Y2Mo2O7 has puzzled physicists for nearly three decades. Free of bulk disorder within the resolution of powder diffraction methods, it is thought that th…
