Title: Ultrasensitive detection enabled by nonlinear magnetization of nanomagnetic labels

The magnetically soft, disk-shaped particles reveal a strong nonlinearity of the magnetization process due to irreversible transitions from the spin vortex to single-domain configuration, enabling their ultrasensitive detection in high-background environments.
