Work Description

1) Production of magnetic materials from materials in the form of tapes and / or micro-and nanostructured powder. Study of kinetics of crystallization of metallic glasses. Studies of microstructure, mechanical properties and electromagnetic characterization of materials.
Implementation of hard and soft ferromagnetic materials in dust or powder metallurgy industries tapes, power tools, manufacture of permanent magnets, energy, etc.

2) Production and study of magnetic and transport properties in magnetic multilayers of thin films (applied to spin valves, and biosensors) and micrometric ferromagnetic powders.

The project covers both the production of materials of interest by techniques of rapid solidification (melt-spinning, centrifugal atomization) and multilayer deposition (evaporation, sputtering and / or laser ablation). Also determined the structural properties consistent techniques (electron microscopy, X-ray diffraction and Mössbauer spectroscopy). The magnetic and transport properties are measured on computers accessible to the group own or through partnerships.
Is a correlation between the materials and processes used to produce the properties achieved, looking to optimize their response according to specific technological need. To achieve this goal, as an analytical tool used the FORC diagrams technique, which identifies the various contributions of the magnetic domains in the hysteresis of the material. This technique is well suited for the analysis of the magnetic response of ferromagnets that have compositional and structural changes at micro and submicron scales, as well as for the design of devices that use it.
