- Abstract:
-
We present the results of muon-spin-relaxation experiments for two materials which show geometric frustration. ZnCr22O4 has a spinel structure with S = 3/2 spins on a lattice of corner-sharing tetrahedra. Our experiments show that a local magnetic field which is quasi-static on the muon timescale develops below Tc = 12.5 K, a transition which has been associated with a three-dimensional analogue of the spin-Peierls transition. In contrast, Gd3Ga5O12 has a garnet structure with S = 7/2 spins a...
