Abstract
We have investigated the critical behavior in amorphous Fe85Sn5Zr10 alloy ribbon prepared using a singleroller meltspinning method This alloy shows a secondorder magnetic transition from paramagnetic to ferromagnetic FM state at the Curie temperature T C ∼306 K To obtain more information on the features of the magnetic transition a detailed critical exponent study was carried out using isothermal magnetization M H T data in the vicinity of the T C Modified Arrott plot Kouvel–Fisher plot Widom’s scaling relation and critical isotherm analysis techniques were used to investigate the critical behavior of this alloy system around its phase transition point The values of critical exponents determined using the above methods are selfconsistent The estimated critical exponents are fairly close to the theoretical prediction of the threedimensional 3D Heisenberg model implying that shortrange FM interactions dominate the critical behavior in amorphous Fe85Sn5Zr10 alloy ribbon
