Abstract
CopMg1-p is a diluted fcc antiferromagnet that can be prepared in isostructural form over the entire 0 < p < 1 range. Magnetic susceptibility data indicate a percolation threshold at p = 0.13, and additionally reveal a crossover effect at p ≈ 0.45. We present results of neutron diffraction studies which confirm that the crossover behavior reflects a transition from a LRO to a SRO state.
