Key Points

To numerically determine the exchange interactions that drive non-collinear magnetism in YBaCuFeO5.
Performed numerical analysis of exchange interactions in YBaCuFeO5.
Used temperature-dependent neutron diffraction to determine experimental propagation vector.

Experimental data from neutron diffraction supported the modeling findings.

Abstract

A numerical determination of exchange interactions governing frustration-driven non-collinear magnetism in YBaCuFeO5 is presented. Temperature-dependent neutron diffraction provides the experimental propagation vector, which is mapped onto a Heisenberg model, and...
