  The creation of disordered hyperuniform materials with potentially
extraordinary optical properties requires a capacity to synthesize large
samples that are effectively hyperuniform down to the nanoscale. Motivated by
this challenge, we propose a fabrication protocol using binary
superparamagnetic colloidal particles confined in a 2D plane. The strong and
long-ranged dipolar interaction induced by a tunable magnetic field is free
from screening effects that attenuates long-ranged electrostatic interactions
in charged colloidal systems. Specifically, we find a family of optimal size
ratios that makes the two-phase system effectively hyperuniform. We show that
hyperuniformity is a general consequence of low isothermal compressibilities,
which makes our protocol suitable to systems with other long-ranged soft
interactions, dimensionalities and/or polydispersity. Our methodology paves the
way to synthesize large photonic hyperuniform materials that function in the
visible to infrared range and hence may accelerate the discovery of novel
photonic materials.
