Abstract
We connect between the problem of thermodynamics of localized magnetic moments in a Dirac semimetal, the interaction with relativistic electrons leading to the effective ferromagnetic exchange between the moments, and the existing theories dealing with long-range exchange interaction. We point out that the results of high-temperature expansion for the free energy of a dilute ensemble of magnetic impurities in the semimetal performed by V. Cheianov et al. [Phys. Rev. B 86, 054424 (2012)] give an indication to the existence of a new disordered fixed point in such model.
