Abstract

We study the magnetization dynamics of nanomagnetic beads with a diameter ranging from 80 to 250 nm in frequency and time domains using a high-resolution elliptical planar Hall effect (EPHE) sensor integrated with a fluidic channel. We find that the dynamics are well described with Cole-Cole and exponential decay models for frequency and time domains, respectively. We discuss the potential use of EPHE sensors in lab-on-a-chip applications.
