Experimental Study of Microwave Permeability of FeCoBSi Thin Films Prepared on Thin Flexible Substrates
The microwave permeability of FeCoBSi thin films prepared on thin flexible substrates is studied.The film as deposited showed as an amorphous and isotropic structure in film plane.The permeability is measured in the frequency range of 0.518 GHz using coaxial techniques.The paper deals with two different technological methods in preparing the spiral measuring sample.Alteration of the technological process allows the microwave properties of the thin films to be varied.The microwave permeability of thin film wound with FeCoBSi layer inward is significantly larger than that of the thin film wound with FeCoBSi layer outward.The reason is attributed to varied types of stresses are caused at the process of spiral sample preparing.The stress affect the measured values of permeability by changing the orientation of in-plane magnetic moments.Therefore,the effect of stress could be avoided or be rationally used in our study.
