Complex antiferromagnetic order in the Cd6 R approximants to the i- R-Cd quasicrystals
Abstract
The observation of antiferromagnetic order in the Cd6 R (R = rare earths) approximants to the recently discovered related i- R-Cd quasicrystals provides new and exciting opportunities to unravel the nature of magnetism in these materials. We present single-crystal studies employing x-ray and neutron scattering that revealed complex antiferromagnetism in the Cd6 R approximants. Resolution-limited magnetic Bragg peaks have been observed at lattice points forbidden by the center-symmetry and at incommensurate positions demonstrating long-range antiferromagnetic correlations between the R moments.
