One-Dimensional Quantum Magnetism in the S = 1/2 Mo(V) system, KMoOP2O7

Aly H. Abdeldaim, Alexander A. Tsirlin, Jacques Ollivier +5

We present a comprehensive experimental and ab-initio study of the $S=1/2$ Mo${}^{5+}$ system, KMoOP${}_2$O${}_7$, and show that it realizes the $S=1/2$ Heisenberg chain antiferromagne…
