“…Amorphous magnetic materials continue to be of fundamental and technological interest due to a number of appealing properties. They typically have low coercivities and reduced electrical conductivity when compared to their crystalline counterparts, opening up a wide variety of potential applications both in bulk [1] and thin film form [2][3][4], especially since properties can be changed within wide ranges by altering the composition. Additionally, Sebastian George and Krisztina Kádas have contributed equally to this work.…”

Using a combination of extended X-ray absorption fine structure measurements, stochastic quenching (SQ) calculations and Voronoi tessellation analysis, the local atomic environments in thin films of amorphous Sm x Co 1Àx (x ¼ 0.10, 0.22 and 0.35) are investigated and also compared with crystalline stoichiometric Sm-Co alloys of similar compositions. It is found that the variations in local environment around Co atoms in the amorphous films increase with increasing x and that none of the films exhibit any pronounced short-range order around the Sm atoms. There are, however, signs of clustering of Sm atoms in the SQ-generated simulated amorphous materials. Furthermore, good agreement is observed between experimentally obtained parameters, e.g., interatomic distances and coordination numbers, and those extracted from the simulated alloys. This is a strong indication that SQ provides a powerful route to reliable local structure information for amorphous rare earth-transition metal alloys and that it could be used for designing materials with properties that meet the demands of specific applications.

“…Induced magnetic anisotropy change in field annealing temperature and time can be controlled [22]. We are focused on an annealing under longitudinal field sample for a uniaxial anisotropy [23,24] ensuring the presence of walls 180 ° parallel to the axis of the Ribbon. An annealing under longitudinal field (magnetic field parallel to a magnetic path direction, i.e., to a ribbon axis) very strongly promotes the emergence of large walls to 180 degrees.…”

Abstract. This work concerns the study of soft iron-based magnetic materials. More specifically, concerning based iron amorphous materials, it will be done by combining structure and magnetic properties while acting on various parameters, by annealing to characterize the nanocrytallization. An experimental approach of magnetic properties is applied to the amorphous or nanocrystalline ultra soft materials evaluation of power losses, permeability as properties of the cycle of hysteresis. According to the scale of constraints and the nature of heat treatment (without magnetic field or magnetic field), it is induced an anisotropy which changes the magnetization properties. Thus, for ferromagnetic amorphous alloys, the anisotropy induced constraints is eliminated giving rise to a uniaxial anisotropy. FeBSi amorphous type materials can therefore, after introduction of copper (multiplication of germs) and niobium (growth inhibition), get nanocrystallized compositions of Fe 73,5 Cu 1 Nb 3 Si 13,5 B 9 after annealing around of 500 -600 ° C.
