英文摘要Critical phenomenon of the noncentrosymmetric Cr11Ge19, which exhibits an itinerant ferromagnetic ground state, is investigated by scaling of the magnetic entropy change [Delta S-M(T,H)]. It is found that parameters delta(FWHM) (the full width at half maximum),Delta S-M(max) (the maximum of the magnetic entropy change), and RCP (the relative cooling power) of Delta S-M(T) are governed by the power law of critical exponents. With the critical exponents, Delta S-M(T,H) curves are scaled into a universal curve independent of temperature and field, which suggests that the magnetic transition is of a second order type. The universal collapse of Delta S-M(T,H) indicates that the critical behavior of Cr11Ge19 can be well described by the scaling laws for the critical phenomenon. Moreover, the Delta S-M follows the power law of H-n with n(T,H)=dln vertical bar Delta S-M vertical bar/dln(H). The temperature dependence of n values reach minimum at similar to 71.5 K. Based on the magnetic specific change Delta C-p(T,H), the actual magnetic transition temperature is strictly determined as T-C=71.3 +/- 0.2 K for the single crystal Cr11Ge19. (C) 2016 Elsevier B.V.
