Non-magnetic ion site disorder effects on the quantum magnetism of a spin-1/2 equilateral triangular lattice antiferromagnet
Q. Huang, R. Rawl, W. W. Xie +12
With the motivation to study how non-magnetic ion site disorder affects the quantum magnetism of Ba3CoSb2O9, a spin-1/2 equilateral triangular lattice antiferromagnet, we performed…
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…
High pressure sequence of Ba_3NiSb_2O_9 structural phases: new quantum spin-liquids based on Ni^{2+}
J. G. Cheng, G. Li, L. Balicas +4
By using a high pressure, high temperature (HPHT) technique, the antiferromagnetically ordered ( = 13.5 K) 6H-A phase of BaNiSbO was transformed into two new gaple…
Magnetic field induced quantum phase transition of the antiferromagnet
S. Nellutla, M. Pati, Y. -J. Jo +11
The magnetic properties of alkali-metal peroxychromate KNaCrO are governed by the pentavalent chromium cation, Cr. Specific heat, magnetocalorimetry, ac ma…
Surface Reconstruction of Hexagonal Y-doped HoMnO3 and LuMnO3 studied using low-energy electron diffraction
R. Vasic, J. T. Sadowski, Y. J. Choi +5
We have investigated the (0001) surfaces of several hexagonal manganite perovskites by low-energy electron diffraction (LEED) in order to determine if the surface periodicity is di…
Itinerant spin excitations near the hidden order transition in URu2Si2
J. A. Janik, H. D. Zhou, Y. -J. Jo +12
By means of neutron scattering we show that the high-temperature precursor to the hidden order state of the heavy fermion superconductor URuSi exhibits heavily damped i…
AC susceptibility and V NMR study of MnVO
S. -H. Baek, K. -Y. Choi, A. P. Reyes +6
We report V zero-field NMR of manganese vanadate spinel of MnVO, together with both ac and dc magnetization measurements. The field and temperature dependence of ac…
