| Abstract | The magnetoresistance (MR) and the superconducting transition temperature T c as well as the longitudinal and the transverse magnetic moments are studied in order to find an underlying cause for the inverse spin switch behavior of bare Py/Nb/Py trilayers. Our measurements consistently show that the increase of MR and the decrease of T c in the case of the antiparallel alignment between the magnetizations of the two Py layers (AP state) compared to those in the parallel alignment (P state), which is known as the inverse spin switch behavior, are largely due to stray field from the domain walls in the domain state that occurs during the AP state. The influence of stray field on the MR and the T c shift between the AP and P state is measured in the bridges with each axis oriented at various angles phi with respect to the magnetization easy axis. With increasing phi from 0deg to 90deg, T c shift between the AP and P state is almost constant around 5 mK up to phi = 54deg, then becomes 11 mK when phi = 72deg, but is reduced to 2 mK for phi = 90deg . In addition, the effect by the stray field not originating in the domain walls is observed outside the domain states in the MR and in the transverse magnetic moment measurements. |

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.
