Thermal effects versus spin nematicity in a frustrated spin- 1 2 chain

M. Pregelj、A. Zorko、Denis Arčon 等 8 位作者2020-08-05Physical review. B./Physical review. B

The spin-nematic phase is an intriguing state of matter that lacks usual long-range dipolar order, yet it exhibits higher multipolar order. This makes its detection extremely difficult and controversial. Recently, nuclear magnetic resonance (NMR) has been proposed as one of the most suitable techniques to confirm its…
