Hyperscaling analysis of a disorder-induced ferromagnetic quantum critical point in Ni${}_{1-x}$Rh${}_x$ with $x=0.375$

Abstract

Here we report on hyperscaling analysis on thermodynamic measurements as a function of temperature and magnetic field for Ni${}_{1-x}$Rh${}_x$ with $x=0.375$ where a ferromagnetic quantum critical point has been recently identified [Phys. Rev. Lett. $\text{124}$, 117203 (2020)]. The obtained critical exponents agree well with the theory proposed by Belitz, Kirkpatrick, and Vojta for disorder tuned quantum critical point in the preasymptotic region.
