Monoclinic distortion and magnetic coupling in the double perovskite Sr sub(2-x)Ca sub(x)YRuO sub(6)

Monoclinic distortion and magnetic coupling in the double perovskite Sr sub(2-x)Ca sub(x)YRuO sub(6)

This work investigates in the insulating double perovskites Sr sub(2-x)Ca sub(x)YRuO sub(6). We address the angular dependence of the strength of the magnetic coupling due to the deviation from planarity of the basal layers of the monoclinic structure, characterized by the in-plane angle alpha >T...

Zusammenfassung:This work investigates in the insulating double perovskites Sr sub(2-x)Ca sub(x)YRuO sub(6). We address the angular dependence of the strength of the magnetic coupling due to the deviation from planarity of the basal layers of the monoclinic structure, characterized by the in-plane angle alpha >T sub(M) and the enhancement of magnetic frustration for T
