Spin wave excitations in the tetragonal double perovskite Sr${}_2$CuWO${}_6$

H. C. Walker, O. Mustonen, S. Vasala +2

Sr${}_2$CuWO${}_6$ is a double perovskite proposed to be at the border between two and three dimensional magnetism, with a square lattice of $S=\frac{1}{2}$ Cu${}^{2+}$ ions. We have use…
