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 …

Rare earth-based materials have played a central role in recent efforts to understand the
very unconventional behavior of geometrically frustrated magnetic materials. In particular …

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 …

Recent experiments suggest that the Ising pyrochlore magnets Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O
7 display qualitative properties of the nearest-neighbor “spin ice” model. We discuss the …

Inelastic magnetic neutron scattering reveals a localized spin resonance at 4.5 meV in the
ordered phase of the geometrically frustrated cubic antiferromagnet ZnCr 2 O 4. The …

Nous présentons une introduction non technique de la théorie des aimants avec une
frustration géométrique importante, nous concentrant sur les aimants sur réseaux avec …

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 …

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

The family of magnetic rare-earth pyrochlore oxides R 2 M 2 O 7 plays host to a diverse
array of exotic phenomena, driven by the interplay between geometrical frustration and spin …

We describe magnetization measurements on the heavy rare earth titanate pyrochlores R 2
Ti 2 O 7, where R= Gd, Dy, Ho, Er, Yb, in the temperature range 1.8-300 K, and the field …
