| Abstract | The purpose of the present work is to investigate the spin dynamics of nanoscale junction formed of diluted ferromagnetic semiconductor as two leads and a curved semiconducting nanowire (NW). This NW is zinc oxide (ZnO) nanostructure, since it exhibits piezoelectric property. The spin transport characteristics of such junction is investigated by deducing the spin current for both parallel and antiparallel spin alignments using the effective mass method and Floquet theory. The effect of strain, generated due to bending the NW, on the spin current is investigated. Rashba spin-orbit interaction, the influence of the photon energy of the induced ac-field and magnetic field are considered. Numerical calculations show that the spin current, for both parallel and antiparallel spin alignments, varies with the induced strain strongly. This variation might be due to piezoelectric effect. Also, the strain gauge factor is calculated. Results for large gauges factor may find applications in different fields of nanotechnology. Results show that the spin transport characteristics are highly sensitive to strain mainly due to the shift in Fermi energy due to piezoelectric effect. Also, results show that the variation of Young's modulus of ZnO NW with strain and it might be monitored by giant magnetoresistance. |

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.
