Frustrated Order by Disorder: the Pyrochlore Antiferromagnet with Bond Disorder
L. Bellier-Castella, M. J. P. Gingras, P. C. W. Holdsworth +1
The classical Heisenberg antiferromagnet on the pyrochlore lattice is macroscopically and continuously degenerate and the system remains disordered at all temperatures, even in the…
Magnetic and Thermodynamic Properties of the Collective Paramagnet-Spin Liquid Pyrochlore Tb2Ti2O7
M. J. P. Gingras, B. C. den Hertog, M. Faucher +5
In a recent letter [Phys. Rev. Lett. {\bf 82}, 1012 (1999)] it was found that the Tb magnetic moments in the TbTiO pyrochlore lattice of corner-sharing tetrahedr…
Observation of Spin Freezing in CaV4O9 and CaV2O5 by uSR
G. M. Luke, Y. Fudamoto, K. M. Kojima +10
We have performed muon spin relaxation and susceptibility measurements of CaV_4O_9 and CaV_2O_5, systems in which spin gap-like behavior has been found. We observe spin freezing in…
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…
