Quantum droplets can emerge in bosonic binary magnetic gases (BMGs) from the interplay of short-and long-ranged interactions, and quantum fluctuations. We develop an extended meanfield theory for this system and use it to predict equilibrium and dynamical properties of BMG droplets. We present a phase diagram and characterize miscible and immiscible droplet states. We also show that a single component self-bound droplet can be used to bind another magnetic component which is not in the droplet regime. Our results should be realizable in experiments with mixtures of highly-magnetic lanthanide atoms.
