Strain Modulation of Microstructure, Magnetic Domains, and Magnetic Properties of Ti/Fe/Ni81Fe19/Fe/Ti Multilayer Thin Films

چکیده

A simple and convenient method is demonstrated in this work by continuously applying uniaxial tensile strains to tune the high-frequency properties of flexible magnetic films. The magnetostriction effect causes anisotropy Ti/Fe/Ni81Fe19/Fe/Ti multilayer film when substrate transitions from convex state planar after preparation. In addition, microstructure, domain morphology, performance pre-strained films are investigated. results show that films’ initial permeability can be monotonically varied over a hundred units, resonant frequency adjusted around 1.5 GHz. films, with their elastic-tunable performance, promising candidate materials for microwave devices.

Effect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films

Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration  levels. X-ray diffraction (XRD) was used  to  investigate  the  films  crystal  structures. The  results  indicate that  if  the  Co  concentration  is  less  that  the  Fe  concentration,  the cubic  structure  appears  in  the  films, while  the  hexagonal  structure dominates when  the C...

Development of magnetic domains in hard ferromagnetic thin films of polytwinned microstructure

Three-dimensional computer simulations are used to examine the development of magnetic domains and migration of domain walls in hard ferromagnetic thin films of polytwinned microstructure. The polytwinned microstructure, consisting of three different orientation variants of the L10 ordered phase with orthogonal c-axes, is characterized by a multi-component long-range order ~LRO! parameter. The ...
