We use a uniaxial garnet film with a magnetic bubble lattice to sort paramagnetic colloidal particles with different diameters, i.e., 1.0 and 2.8 m. We apply an external magnetic field which precesses around an axis normal to the film with a frequency =62.8 s−1 and intensity 3120 A/m Hm. We apply an external magnetic field which precesses around an axis normal to the film with a frequency =62.8 s−1 and intensity 3120 A/m H−1 and intensity 3120 A/m H 6911 A/m. By varying the component of the field Hz normal to the film, we observe that particles of one size are localized around magnetic bubbles while the others are transported through the array. We complement the experimental measurements with numerical simulations to explore the sorting capability for particles with different magnetic moments.6911 A/m.
