jats:pSynthetic antiferromagnetic particles with perpendicular magnetic anisotropy offer a highly desirable platform for use in fluidic applications. This work illustrates their high level of switching field tunability and demonstrates the ability to use particle design to overcome unfavorable hysteretic changes during patterning to manufacture functional, low switching field nanodisks. This makes them ideal candidates for lab-on-chip technologies such as microfluidic sorting or detection devices.</jats:p>
