In a hybrid magnonic system, it is always essential to include at least one magnetic material that supports magnon excitation, regardless of the specific implementation details. The most commonly used magnetic materials include yttrium iron garnet (YIG) and permalloy (Py).A corollary is that photons have much longer coherence lengths, while magnons provide a compact platform for quantum 30 effects and manipulation via interactions. The latter point partly allows the unique niche of magnon squeezing to be discussed here. In essence, the two fields are complementary and can gain from each other.

The two answers given so far are wrong. A magnon is an excitation carrying spin-$1$. A spinon is an excitation carryong spin-$\frac {1} {2}$. This has nothing to do with it being an excitation above a ferro- or antiferromagnet. The difference is much more dramatic, such that magnons are 'normal'/standard, yet spinons are very special.
