Amorphous Materials for Elastic Sensitive Elements of Information-Measurement Systems

Article presents the results of research of amorphous gas-thermal iron based coatings magnetic properties that are the most promising in terms of their application in information-measurement systems. It was established that magnetic properties of amorphous iron Fe78Si10B12 are comparable with properties of the best crystalline magnetic soft materials. There is practically no hysteresis on magnetization curves of amorphous coatings, indicating low coercive force and rectangularity of hysteresis loop. The Curie point of tested covering is practically determined by the temperature of transition to the crystalline state. Noted that magnetostriction is common for coating as well as for crystalline soft magnetic materials, but more strongly marked. Amorphous ferromagnetic coatings feature low sensitivity of their magnetic properties to mechanical stress. The level of mechanical properties and the ability to distribute acoustic waves with low energy loss are of interest for manufacturing of elastic sensitive elements.
