Abstract
The impact of chemical doping of the type Sr2−xAxYRuO6 (A=Ca, Ba) on the low temperature magnetic properties of Sr2YRuO6, probed using variable temperature magnetic susceptibility, neutron diffraction and heat capacity measurements, are described. Specific-heat measurements of un-doped Sr2YRuO6 reveal two features at ∼26 and ∼30 K. Neutron scattering measurements at these temperatures are consistent with a change from a 2D ordered state to the 3D type 1 AFM state. Magnetic and structural studies of a number of doped oxides are described that highlight the unique low temperature behavior of Sr2YRuO6 and demonstrate that doping destabilizes the intermediate 2D ordered state. © 2017 Elsevier Inc.
