Magnetic Frustration on a Kagomé Lattice in R$\_3$Ga$\_5$SiO$\_14$ Langasites with R = Nd, Pr

P. Bordet, I. Gelard, K. Marty +6

In the R$\_3$Ga$\_5$SiO$\_14$ compounds, the network R of rare earth cations form well separated planes of corner sharing triangles topologically equivalent to a kagomé latti…
