Spiral Spin Liquid State in the Corrugated Honeycomb Lattice of CaMn $_{2}$ P $_{2}$

Farhan Islam, Nikita D. Andriushin, Thaís V. Trevisan +9

CaMn $_{2}$ P $_{2}$ exemplifies the realization of a frustrated $J_{1}$ - $J_{2}$ - $J_{3}$ Heisenberg model of a corrugated honeycomb magnetic lattice. Previous studies show that below the Néel t…
