Description
Single crystals of the disordered perovskite-type Sr(Fe sub(0.766)W sub(0.234))O3 have been grown from a flux of SrCl2. The crystals grew with a cubical habit with distinct (100) faces. Magnetic measurements indicated antiferromagnetic behavior or weak-ferromagnetic one with very small spontaneous magnetization (-- 0.028 emu/g). The existence of Fe4+ was suggested by the Moessbauer technique. The Neel temperature is 193 K. The differences of structural, magnetic properties and Moessbauer effect between Sr(Fe sub(0.766)W sub(0.234))O3 and Sr(Fe sub(2/3)W sub(1/3))O3 are generally explained by assigning the valence states of the two samples as Sr(Fe sub(0.468)sup(4+)Fe sub(0.298)sup(4+)W sub(0.234)sup(6+))O3 and Sr(Fe sub(1/3)sup(3+)W sub(2/3)sup(6+))O3 respectively.
