Claims

C1strongest claim

A macrospin model incorporating bilinear and biquadratic coupling reproduces the experimental data and supports a phase diagram analysis identifying non-collinear configurations.

C2weakest assumption

The macrospin approximation remains valid despite rough interfaces and that the biquadratic term can be treated as an independent fitting parameter without deriving it from the observed interface roughness.

C3one line summary

Biquadratic exchange coupling in weakly antiferromagnetically coupled Fe/Ti superlattices produces two-step hysteresis loops and non-collinear magnetic configurations, as reproduced by a macrospin model.
