| 英文摘要 | A thorough investigation was carried out to analyze the magnetic critical properties of single crystals belonging to the HfFe 6 Ge 6 -type structure. MgMn 6 Sn 6 exhibit a ferromagnetic transition below T C approximate to 300 K. The magnetization measurements were analyzed around the phase transition temperature of this ferromagnetic material for two different orientations: H//ab and H//c. Using Kouvel-Fisher method, we can determine critical exponents beta, gamma, and delta in this study. To evaluate accuracy of these values, the scaling equation m = f +/- (h ) and Widom scaling law delta = 1 + gamma / beta were applied. Critical exponents gamma = 1.191 +/- 0.007 at T C = 300.92 K, beta = 0.326 +/- 0.003 at T C = 300.96 K, and delta = 4.653 with T C approximate to 300 K indicate that the three-dimensional Ising model ( beta = 0.325, gamma = 1.24, and delta = 4.82) is the better model for H//ab. The mean-field and 3D -Heisenberg models were the best models below T C and above T C for H//c, respectively. The MgMn 6 Sn 6 single crystal exhibits a notable anisotropic transition in its magnetic phase according to all experimental findings. The presence of an anisotropic state with short-range order in the ferromagnetic system are revealed by analyzing electron spin resonance (ESR) spectroscopy. Our research provides experimental proof of a holistic comprehension regarding the magnetic phasetransition characteristics demonstrated by MgMn 6 Sn 6 . |
