| description | Polycrystalline samples of the n=1 Ruddlesden-Popper system Pr3-xSr1+xCrNiO8 have been synthesized over the composition range 0.0<x≤1.0 (d.c.="" (x-ray,="" a.c.).="" all="" an="" and="" appropriate="" been="" by="" ceramic="" characterized="" combination="" compositions="" diffraction="" either="" electron)="" from="" have="" having="" magnetometry="" method="" methods="" neutron="" of="" or="" solution.="" the="" they="" x="">0.1 adopt the tetragonal space group I4/mmm; Pr2.9Sr1.1CrNiO8 adopts the orthorhombic space group Fmmm. There is no evidence of Cr/Ni cation ordering in any composition. A maximum in the zero-field cooled magnetic susceptibility is observed at a temperature Tf that decreases with increasing Sr content; 52≤Tf (K)≤13. The frequency dependence of Tf observed in a.c. susceptibility measurements, together with the analysis of neutron diffraction data, suggests that the atomic magnetic moments in these compositions adopt a spin-glass-like state below Tf. © 2008 Elsevier Inc.
