Unusual spin fluctuations and magnetic frustration in olivine and non-olivine LiCoPO${}_4$ detected by ${}^{31}$P and ${}^7$Li nuclear magnetic resonance

S. -H. Baek, R. Klingeler, C. Neef +3

We report ${}^{31}$P and ${}^7$Li nuclear magnetic resonance (NMR) studies in new non-olivine LiZnPO${}_4$-type LiCoPO${}_4^{\text{tetra}}$ microcrystals, where the Co${}^{2+}$ ions are tetr…
