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…
Transition to Long Range Magnetic Order in the Highly Frustrated Insulating Pyrochlore Antiferromagnet Gd_2Ti_2O_7
N. P. Raju, M. Dion, M. J. P. Gingras +2
Experimental evidence from measurements of the a.c. and d.c. susceptibility, and heat capacity data show that the pyrochlore structure oxide, Gd_2Ti_2O_7, exhibits short range orde…
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…
Static Critical Behavior of the Spin-Freezing Transition in the Geometrically Frustrated Pyrochlore Antiferromagnet Y2Mo2O7
M. J. P. Gingras, C. V. Stager, N. P. Raju +2
Some frustrated pyrochlore antiferromagnets, such as Y2Mo2O7, show a spin-freezing transition and magnetic irreversibilities below a temperature Tf similar to what is observed nonl…
