Doping-induced quantum cross-over in Er${}_2$Ti${}_{2-x}$Sn${}_x$O${}_7$

Masae Shirai, Rafael S. Freitas, Jorge Lago +3

We present the results of the investigation of magnetic properties of the Er${}_2$Ti${}_{2-x}$Sn${}_x$O${}_7$ series. For small doping values the ordering temperature decreases linearly wi…
