Abstract
The critical properties of flux-grown single-crystalline quasi-two-dimensional weak itinerant ferromagnet were investigated by bulk dc magnetization around the paramagnetic to ferromagnetic phase transition. Critical exponents with a critical temperature K and with K are obtained by the Kouvel-Fisher method whereas is obtained by a critical isotherm analysis at K. With these obtained exponents, the magnetization-field-temperature curves collapse into two independent curves following a single scaling equation around , suggesting the reliability of the obtained exponents. Additionally, the determined exponents of exhibit an Ising-like behavior with a change from short-range order to long-range order in the nature of magnetic interaction and with an extension from two to three dimensions on cooling through .
