Finite size effects on Weyl semimetal NdSiAl

In recent years exotic relativistic quasiparticles have been found to exist in the band structure of different materials, like Dirac fermions in graphene, or topological insulating states in topological insulators. Recently it was shown for first time that one of such band configurations to have an effect on a collective property like the magnetism. In NdAlSi, it was reported that the existence of Weyl nodes was in the root of a magnetic helical ordering. The objective of this experiment is to test the effect of size reduction in such helical order. This experiment will shed light into the effect of electronic confinement in the relativistic quasiparticles.
