Doping of Dion-Jacobson phases with quantum magnetic ground states

Abstract: Dion-Jacobson (DJ) [layered perovskites A'[An-1BnO3n+1], where A' is an alkali cation, A is an alkaline earth or rare earth cation and B is a transition metal) have a wide range of functionalities. (CuCl)LaNb2O7 behaves as a system of ferromagnetically coupled Shastry-Sutherland quantum spin singlets. We have prepared Dion-Jacobson layered perovskites (CuCl)La1–xSrxNb2O7 (x = 0, 0.1 and 0.15) via topotactic ion-exchange reactions with intermediate compounds RbLa1–xSrxNb2O7. Replacing some La3+ ions with Sr2+ ions in the perovskite precursor is expected to disrupt the quantum singlet state and perhaps lead to a transition from insulator to metallic behaviour. High resolution powder neutron diffraction data are required to discover how Sr-doping affects the orthorhombic superstructure and whether any magnetic order emerges at low temperature as a result of dimer-breaking.
