Magnetic excitations of the gapped quantum spin dimer antiferromagnet Sr${}_3$Cr${}_2$O${}_8$

Diana L. Quintero-Castro, Bella Lake, Elisa M. Wheeler +8

Sr${}_3$Cr${}_2$O${}_8$ consist of a lattice of spin-1/2 Cr${}^{5+}$ ions, which form hexagonal bilayers and which are paired into dimers by the dominant antiferromagnetic intrabilay…
