= 0.3 - 0.375) close to a quantum phase transition*

We studied the critical behavior of itinerant ferromagnets Ni_1-xRh_x with x = 0.3 - 0.375 based on the Arrott-Noakes scaling analysis. The ferromagnetic ordering temperature is continuously suppressed to zero at a critical concentration x_c ~ 0.375. For x = 0.3, mean-field like exponents β ~ 0.5,γ ~ 1.5, and δ ~ 3 are observed. With increasing x, critical exponents vary smoothly and reach at β ~ 0.6,γ ~ 0.7, and δ ~ 2.3 for x = 0.37. The evolution of exponents with x and the exponent values close to x_c cannot be described by any known universality class for classical models. The possible explanation for the trend of exponents is that, close to x_c, strong quantum fluctuations enhance the role of disorder and drive the system to a new strong-coupling regime.
