Metglas 2826B—Transport, magnetic and thermal properties

• We report Hall resistivity, magnetization, heat capacity, and electrical resistivity studies on Metglas2826B (Fe29Ni49P14B6Si2) spanning the temperature regime 77 to 800K. The critical exponents for this system are found to be β = 0.40 ± 0.01, δ = 5.25 ± 0.10, and γ = 1.7 ± 0.1. The magnetic isotherms fit into universal scaling functions over a rather wide range of temperature both above and below Tc. The specific heat exhibits a sharp peak at Tc. The temperature derivative of the electrical resistivity has a marked change at Tc. Although Tc increases slightly on thermal cycling to higher temperatures, the critical exponents are not influenced by this.
