Experimental evidence for the coupling of Li-motion and structural distortions in LiMnPO${}_4$

Christian Rudisch, Hans-Joachim Grafe, Jochen Geck +5

We present a detailed ${}^7$Li- and ${}^{31}$P-NMR study on single crystalline LiMnPO${}_4$ in the paramagnetic and antiferromagnetic phase (AFM, $T_N\sim$ 34 K). This allows us to dete…
