Abstract

The objective of this proposal is the acquisition of a cryogenic-free system for the measurement of magnetization and of other physical properties, which will eliminate the need for the frequent procurement of liquid helium. The acquisition of this system will resolve the problem of magnetic properties measurement that the Superconductivity Group of the Department of Materials Engineering of the USP School of Engineering at Lorena has faced for more than ten years. Among the relevant scientific aspects of the various associated and complementary projects, the use of magnetic measurements plays an important role in the following activities: i) the investigation of new superconducting materials; ii) the study of the quasi-unidimensional structure of molybdates; iii) the study of magnetostriction in iron-based alloys; iv) the study of magnetic superlattices and quantum structures; v) the study of polymers with magnetic inclusion compounds; vi) the study of the dynamics of vortices and the optimization of flux trapping in superconductors; and vii) the study of the magnetic properties of various materials. The team includes 19 researchers involved in the associated and complementary projects underway at renowned teaching institutions and research institutes in the Vale do Paraíba region. All of the researchers in the group are intensely involved in scientific activity, the great majority being recipients of Productivity in Research grants from the National Council for Scientific and Technological Development (CNPq), and maintain active, significant international affiliations. In addition, they are advisors to a number of young investigators and graduate students. Our Department has the infrastructure and technical staff necessary for the installation and maintenance of the equipment requested by the FAPESP Multi-User Equipment Program. (AU)
