Within the past 20 years or so, there has occurred an explosion of interest in the magnetic
behavior of pyrochlore oxides of the type A 2 3+ B 2 4+ O 7, where A is a rare-earth ion and …

Publisher Summary This chapter discusses percolation theory as well as spin-glass
phenomena, the former of which is used to understand subjects as diverse as fluid flow in …

The current state of efforts to understand the phenomenon of geometric magnetic frustration
is described in the context of several key materials. All are transition metal oxides which …

The magnetothermodynamics of strongly frustrated classical Heisenberg antiferromagnets
on kagome, garnet, and pyrochlore lattices is examined. The field induced adiabatic …

We report the observation of the longitudinal spin Seebeck effect in paramagnetic insulators.
By using a microscale on-chip local heater, we generate a large thermal gradient confined to …

The Coulomb phase, with its dipolar correlations and pinch-point–scattering patterns, is
central to discussions of geometrically frustrated systems, from water ice to binary and mixed …

Experimental evidence from measurements of the ac and dc susceptibility, and heat-
capacity data show that the pyrochlore structure oxide, Gd 2 Ti 2 O 7, exhibits short-range …

Frustrated magnetic materials are promising candidates for new states of matter because
lattice geometry suppresses conventional magnetic dipole order, potentially allowing …

Liquids are expected to crystallize at low temperature. The only exception is helium, which
can remain liquid at 0 K, owing to quantum fluctuations,. Similarly, the atomic magnetic …

Classical Heisenberg antiferromagnets on two-dimensional kagome and three-dimensional
hyperkagome lattices are investigated by Monte Carlo simulations. For both models the …
