Quasi-one-dimensional uniform spin-$\frac{1}{2}$ Heisenberg antiferromagnet KNaCuP${}_2$O${}_7$ probed by ${}^{31}$P and ${}^{23}$Na NMR

S. Guchhait, Qing-Ping Ding, M. Sahoo +4

We present the structural and magnetic properties of KNaCuP${}_2$O${}_7$ investigated via x-ray diffraction, magnetization, specific heat, and ${}^{31}$P NMR and ${}^{23}$Na NMR measuremen…
