Reentrant behavior and possible $2/3$ magnetization plateau on the double-trillium langbeinite K$_2$Ni$_2$(SO$_4$)$_3$

Ivica \v{Z}ivkovi\'c, Johannes Reuther, Mat\'ias G. Gonzalez, Yurii Skourski

K2Ni2(SO4)3 shows a reentrant 2/3 magnetization plateau from a 1/3 state on the strong trillium lattice plus full polarization on the weak one.

Claims

C1strongest claim

we reveal a signature of a 2/3 magnetization plateau consisting of a 1/3 phase on strong-TL and a fully polarized phase on weak-TL. Although in the classical limit no plateau is expected, we find a very prominent dome structure reflecting the tendency of the system to stabilize this particular spin configuration.

C2weakest assumption

The assumption that the observed magnetization feature corresponds to the proposed 1/3-plus-full polarization state and that classical Monte Carlo sufficiently captures the relevant physics for an S=1 quantum system near a spin-liquid regime.

C3one line summary

K2Ni2(SO4)3 exhibits reentrant behavior and a possible 2/3 magnetization plateau arising from a 1/3 state on the strong trillium lattice and full polarization on the weak lattice, as indicated by high-field data and classical simulations.
