The magnetization relaxations of three different types of geometrically frustrated magnetic systems have been studied with the same experimental procedures as previously used in spin glasses. The materials investigated are Y2Mo2O7 (pyrochlore system), SrCr8.6Ga3.4O19 (piled pairs of Kagome layers) and (H3O)Fe3(SO4)2(OH)6 (jarosite compound). Despite a very small amount of disorder, all the samples exhibit many characteristic features of spin glass dynamics below a freezing temperature Tg, much…

Spin-Orbital Glass Transition in a Model of a Frustrated Pyrochlore Magnet without Quenched Disorder.
The authors' Monte Carlo simulations detect the power-law divergence of the relaxation times and the negative divergence of both the magnetic and dielectric nonlinear susceptibilities, resolving the long-standing puzzle on the origin of the disorder-free spin glass.
Mean-field phase diagram and spin-glass phase of the dipolar kagome Ising antiferromagnet
We derive the equilibrium phase diagram of the classical dipolar Ising antiferromagnet at the mean-field level on a geometry that mimics the two dimensional Kagome lattice. Our mean-field treatment
Heterogeneous freezing in a geometrically frustrated spin model without disorder: Spontaneous generation of two time scales
By considering the constrained motion of classical spins in a geometrically frustrated magnet, we find a dynamical freezing temperature below which the system gets trapped in metastable states with a
Scaling of Memories and Crossover in Glassy Magnets
It is shown that scaling of magnetic memories with time can be used to classify magnetic glassy materials into two distinct classes, and a systematic study on dilute magnetic alloys with varying magnetic concentration exhibits crossovers among the two glassy states and spin solid.
High-dimensional fractionalization and spinon deconfinement in pyrochlore antiferromagnets
The ground states of Klein type spin models on the pyrochlore and checkerboard lattice are spanned by the set of singlet dimer coverings, and thus possess an extensive ground--state degeneracy. Among

Aging, memory, and nonhierarchical energy landscape of spin jam
It is shown that densely populated frustrated magnets in a spin jam state exhibit much weaker memory effects than spin glasses, and the characteristic properties can be reproduced by a nonhierarchical landscape with a wide and nearly flat but rough bottom.

The model 2d kagome system (H3O)Fe3(SO4)2(OH)6 and the 3d pyrochlore Y2Mo2O7 are two well characterized examples of low-disordered frustrated antiferromagnets which rather than condensing into spin
