Randomness and Frustration in a S = 1/2 Square-Lattice Heisenberg Antiferromagnet

Ellen Fogh, Otto Mustonen, Peter Babkevich +7

We explore the interplay between randomness and magnetic frustration in the series of $S=1/2$ Heisenberg square-lattice compounds Sr${}_2$CuTe${}_{1-x}$W${}_x$O${}_6$. Substituting W for…
