Abstract

Using Monte Carlo simulations, we explore the magnetic phase diagram of the triangular spin tubes coupled with a ferromagnetic inter-tube interaction for CsCrF4. A planar structure of the coupled tubes is topologically equivalent to the Kagome-triangular lattice, which induces nontrivial frustration effects in the system. We particularly find that, depending on the inter-tube coupling, various ordered phases are actually realized, such as incommensurate order, ferromagnetic order, and Cuboc order, which is characterized by the non-coplanar spin structure of the twelve sublattice accompanying the spin chirality breaking. We also discuss a relevance of the results to recent experiments of CsCrF4.
