Abstract
The solid solution Sr3xLa2-3xZn1-xRuxO4 (13 ≤ x ≤ 23) has the tetragonal K2NiF4 structure with a disordered arrangement of Zn2+ and Ru5+ over the octahedral sites. The sample with x = 13 is found to be paramagnetic over the temperature range 6 < T < 296 K. As the ruthenium concentration increases, short-range antiferromagnetic interactions between Ru5+ ions become more important; the magnetic susceptibility shows a maximum at low temperatures when x is larger than the percolation threshold for a nearest-neighbor square lattice (0.59). However, the magnetic irreversibility observed for the samples with x = 12 and 23 indicates that next-nearest-neighbor interactions also play an important role in determining the magnetic properties of these compounds.
