From the blog post:

In this research, the team stacked thin films of two quantum materials together and sent an electrical current through them in a chilled vacuum chamber. The top film was a superconductor, and the bottom one was a magnetic topological insulator.

By sweeping a magnet over the stack, the team was then able to modify the speed of electrons. At certain points, this caused what appeared to be Majorana quasiparticles to emerge in pairs along with electrons. One was always deflected away so that the flow of the individual quasiparticles could be measured.
