Abstract

The critical properties of flux-grown single-crystalline quasi-two-dimensional weak itinerant ferromagnet Cr0.62Te were investigated by bulk dc magnetization around the paramagnetic to ferromagnetic phase transition. Critical exponents β=0.315(7) with a critical temperature Tc=230.6(3) K and γ=1.81(2) with Tc=229.1(1) K are obtained by the Kouvel-Fisher method whereas δ=6.35(4) is obtained by a critical isotherm analysis at Tc=230 K. With these obtained exponents, the magnetization-field-temperature curves collapse into two independent curves following a single scaling equation M|TTcTc|β=f±(H|TTcTc|βδ) around Tc, suggesting the reliability of the obtained exponents. Additionally, the determined exponents of Cr0.62Te 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 Tc.
