| Abstract | Dynamic magnetic susceptibility of a laminated composite of FeSiB/Pb(ZrTi)O3/FeSiB was measured. Alternating magnetic and electric fields in the ultrasonic range were simultaneously applied to excite the first mode of the longitudinal resonant vibrations of the composite sample. Significant enhancement of the susceptibility was observed when both fields had the same phase. However, the susceptibility was reduced by almost two orders of magnitude when the phase between the electric and magnetic field was shifted by 180°. This effect is interpreted in terms of combined magnetomechanical and electromechanical resonances that cause large dynamic strains in the magnetostrictive FeSiB ribbons and give rise to large changes of the magnetization when the strains in the magnetic and piezoelectric act in unison. In contrast, when the excitation fields have different phases, the strains in both materials oppose each other and the magnetoelastic contribution to the susceptibility is suppressed. The phase control of the magnetic susceptibility offers an interesting mechanism for applications, where fast modulation or rapid ON/OFF switching of susceptibility signal is required. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
