TL;DR

This study uses inelastic neutron scattering to confirm ferromagnetic nearest-neighbor interactions and frustration in LiCu2O2, revealing significant double-chain interactions that influence its magnetic structure.

Contribution

It provides new experimental evidence showing double-chain interactions are comparable to single-chain ones, clarifying the frustration mechanism in LiCu2O2.

Findings

Confirmed ferromagnetic nn interactions in single chains

Found double-chain interactions are of similar magnitude to single-chain ones

Revealed double-chain interactions contribute to magnetic frustration

Abstract

Exchanged interactions in recently observed helical structure in LiCu2O2 is probed by inelastic neutron scattering. The main conlusions of Refs. [1,2] are confirmed: nn interactions in single chains are ferromagnetic and frustrated by nnn antiferromagnetic ones. However, in apparent disagreement with Refs. [1,2] double-chain interactions are found to be of the same order of magnitude as the single-chain ones, and thus involved in the frustration mechanism. [1] Drechsler et al., cond-mat/0411418. [2] A.
