It is not possible for a group of particles to have a divergent field when none of the individual particles have a divergent field.
This is not less interesting because it's "just a quasi-particle".
This is 2d surface behavior of a solid material. The magnetic fields on the 2d surface act as if there are mobile particles with magnetic charge moving around on the surface.

This is far less interesting for two reasons:
1. No new particles for starters.
2. This is not first time magnetic monopoly quasiparticles have been discovered in materials. Mangetic monopoles have been discovered in materials in the past https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.10..., https://www.nature.com/articles/news.2009.881
Discovering true magnetic monopoly would be biggest discovery in physics since ____. Gauss's law of magnetism violated. This was not it.
