Magnetic transition in the 1D spin-chain system SrCo$_{2}$V$_{2}$O$_{8}$*

We report the $^{51}$V NMR study on the quasi-one-dimensional spin system SrCo$_{2}$V$_{2}$O$_{8}$. Incommensurate antiferromagnetic transition in this material is revealed from the splitting of the spectrum peak from the paramagnetic phase. When applying magnetic fields, spin reorientation is observed before entering the paramagnetic phase for fields both parallel and perpendicular to the c axis. Similar spin reorientation is also observed if by varying the temperature across the Neel temperature. We have obtained the $^{51}$V NMR spectra for three different field angles (0$^{\circ}$, 45$^{\circ}$, 90$^ {\circ}$) between the c axis. A detailed analysis of this antiferromagnetic structure will be discussed.
