| Abstract | In this work, we investigate Zr substitution in Permalloy Ni/sub 80/Fe/sub 20/ thin films in order to control the magnetic properties and then to tune the resonance frequency at lower values with high permeability levels. The structural transition from a crystalline to an amorphous phase, saturation induction, in-plane anisotropy, electrical resistivity, and frequency-dependent permeability are studied for the Zr content ranging from 0 to 17% at. The high-frequency permeability of these (Ni/sub 80/Fe/sub 20/)/sub 1-x/Zr/sub x/ films is first measured in the 0.1-3-GHz range using a permeameter. Assuming a gyroresonance mechanism, the frequency-dependence of the permeability is studied as a function of the magnetization, anisotropy field, and damping parameter deduced from ferromagnetic resonance characterizations. For a Zr concentration of 17%, a resistivity of 260 /spl mu//spl Omega//spl middot/cm is obtained as well as very soft properties (H/sub c/<0.5 Oe). We also show that the permeability is drastically affected by the Zr substitution with a significant shift of the resonance frequency from 600 to 300 MHz, which correlates with the decrease of the saturation induction and a very low anisotropy. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
