SR study of spin freezing and persistent spin dynamics in NaCaNiF
Y. Cai, M. N. Wilson, A. M. Hallas +8
A new pyrochlore compound, NaCaNiF, was recently synthesized and has a single magnetic site with spin-1 Ni. We present zero field (ZF) and longitudinal field (LF) mu…
Incommensurate magnetism near quantum criticality in CeNiAsO
Shan Wu, W. A. Phelan, L. Liu +14
Two phase transitions in the tetragonal strongly correlated electron system CeNiAsO were probed by neutron scattering and zero field muon spin rotation. For = 8.7(3) K,…
Vibrating-coil magnetometry of the spin liquid properties of Tb2Ti2O7
S. Legl, C. Krey, S. R. Dunsiger +4
We have explored the spin liquid state in Tb2Ti2O7 with vibrating coil magnetometry down to 0.04 K under magnetic fields up to 5 T. We observe magnetic history dependence below $T…
Reply to Comment on "Spin Ice: Magnetic Excitations without Monopole Signatures using Muon Spin Rotation"
S. R. Dunsiger, A. A. Aczel, C. Arguello +13
We respond to the comment of Bramwell et al (arXiv:1111.4168v1) to our original publication (S. R. Dunsiger et al, Phys. Rev. Lett. 107, 207207 (2011)), detailing muon spin rotatio…
Spin Ice: Magnetic Excitations without Monopole Signatures using Muon Spin Rotation
S. R. Dunsiger, A. A. Aczel, C. Arguello +13
Theory predicts the low-temperature magnetic excitations in spin ices consist of deconfined magnetic charges, or monopoles. A recent transverse-field (TF) muon spin rotation (muSR)…
Role of commensurate and incommensurate low-energy excitations in the paramagnetic to hidden-order transition of URuSi
P. G. Niklowitz, S. R. Dunsiger, C. Pfleiderer +6
We report low-energy inelastic neutron scattering data of the paramagnetic (PM) to hidden-order (HO) phase transition at in URuSi. While confirming prev…
Phase separation and suppression of critical dynamics at quantum transitions of itinerant magnets: MnSi and (SrCa)RuO
Y. J. Uemura, T. Goko, I. M. Gat-Malureanu +18
Quantum phase transitions (QPTs) have been studied extensively in correlated electron systems. Characterization of magnetism at QPTs has, however, been limited by the volume-integr…
Muon Spin Relaxation Investigation of the Spin Dynamics of Geometrically Frustrated Antiferromagnets Y2Mo2O7 and Tb2Mo2O7 Static Critical Behavior of the Spin-Freezing
S. R. Dunsiger, R. F. Kiefl, K. H. Chow +11
The spin dynamics of geometrically frustrated pyrochlore antiferromagnets Y2Mo2O7 and Tb2Mo2O7 have been investigated using muon spin relaxation. A dramatic slowing down of the mom…
