RbCoCl3 - A Quasi 1-D Ising Magnet | ||
![]() |
||
In the hexagonal perovskite RbCoCl3 1-D antiferromagnetic correlations emerge along Co2+ chains below 90 K. At lower temperature complex interchain interactions set in and give rise to (partial) 3-D magnetic order. Below TN1 = 28 K the spins are aligned parallel to the c-axis, but 1/3 of the chains are uncorrelated from their neighbors. Only below TN2 = 13 K the system achieves a fully ordered state.
This work was carried out in the groups of PD Dr. Karl Krämer (DCBP) and Prof. Dr. Christian Rüegg (PSI) using the facilities SINQ and SLS at PSI, ISIS (UK), and ILL (F). References:
