Summary

Introduction

The increasingly miniaturized devices at high frequencies lead to noise in medical apparats. Application magnetic glass-coated cast amorphous micro and nanowires (GCAMNWs) is considered in articles [1,2,3,4]. That glass-coated amorphous magnetic micro-and nanowires (GCAMNWs) possess very interesting high frequency properties due to the strong magnetoelastic anisotropy which is induced in the fabrication process [5]. The stress effect on the NFMR, that is, the shift of the resonance frequency as a result of a deformation of the object (or organs of the body). The residual tension is characterized by the axial, σ z , radial, σ r , and tangential, σφ , components The value of these stresses depends on the ratio of the radius, Rm, of the metallic kernel to the total microwire radius, Rc:
