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 …

A review of the muon spin rotation and relaxation studies on magnetic materials published
from July 1993 is presented. It covers the investigation of magnetic phase diagrams, that of …

We report a detailed study of the pyrochlore Ho 2 Ti 2 O 7, in which the magnetic ions (Ho
3+) are ferromagnetically coupled with J∼ 1 K. We show that the presence of local Ising …

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 …

We study the low-temperature behavior of the classical Heisenberg antiferromagnet with
nearest neighbor interactions on the pyrochlore lattice. Because of geometrical frustration …

We study the ground-state and low-energy properties of classical vector spin models with
nearest-neighbor antiferromagnetic interactions on a class of geometrically frustrated …

Neutron scattering, muon spin relaxation, and dc susceptibility studies have been carried out
on polycrystalline Tb 2 Ti 2 O 7, a pyrochlore antiferromagnet in which the Tb 3+ moments …

In a recent paper [JS Gardner et al., Phys. Rev. Lett. 82, 1012 (1999)] it was found that the Tb
3+ magnetic moments in the Tb 2 Ti 2 O 7 antiferromagnetic pyrochlore lattice of corner …

Some frustrated pyrochlore antiferromagnets, such as Y 2 M o 2 O 7, show a spin-freezing
transition and magnetic irreversibilities below a temperature T f similar to what is observed in …

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 …
