Narrowly avoided spin-nematic phase in BaCdVO(PO $_{4}$ ) $_{2}$ : NMR evidence

K. M. Ranjith, K. Yu. Povarov, Z. Yan +2

We present a $^{31}$ P nuclear magnetic resonance (NMR) investigation of BaCdVO(PO $_{4}$ ) $_{2}$ focusing on the nearly saturated regime between $μ_{0} H_{c 1}$ = 4.05 T and $μ_{0} H_{c 2}$ = 6.…
