Magnetic characterization services
Person in charge: Jose I. Espeso
This magnetometer is based on a QD-MPMS (SQUID) detector that is able to determine extremelly low magnetization signals present in the material under study. This magnetization can be evaluated under several conditions of external magnetic field and temperature. The core system consists of a superconducting longitudinal solenoid able to generate mangetic fields up to 5 Tesla. The system has also able to precisely control the temperature at the sample space at any value from 2K to 400K with a stability condition of les than 0.1% of oscillation. Pressure cell up to 15 kbar.
The REMAGRAPH ® C is a hysteresigraph for taking quasi-static (DC) measurements on soft magnetic material
The REMAGRAPH ® C allows measuring a variety of materials with different magnetic properties, for example: Soft magnetic steel, Electrical steel, Ferrous alloys, Soft magnetic ferrites, Crystalline Ni-Fe alloys and compounds, Amorphous magnetic materials, Nanocrystalline alloys, Soft magnetic composites (SMC).
X-ray Diffraction characterization services
Person in charge: Manuel De Pedro Del Valle
This service aims to support basic and applied research, in different areas of knowledge; especially on Chemistry, Physics, Geology and Materials Science.
With a long background since 2000, it provides supports to different national and international research group and companies for identification of minerals and other crystalline phases in prospecting for mineral deposits, rocks and industrial minerals, samples of rocks, soils, archaeological remains (ceramics, bones, teeth, etc.), industrial and construction materials, catalysts, industrial refractories, sand, medicines, among others. In addition, the service has been approved by the U.S. Food and Drug Administration (FDA) for testing certain chemicals used in the pharmacological industry.
Equipment
Bruker D8 Advance: Operates with Theta-Theta geometry, with Cu K-alpha radiation and a linear LynxEye detector. It can be used with different sample holders and a spinner to improve the statistics of the measurements. For users who require it, phase identification is carried out using specific software, in combination with the ICDD and COD databases. The results obtained are sent to users in the form of reports, graphs and/or tables. Likewise, this provided information includes the specifications of the used equipment, measuring conditions, methodology for preparing the samples, etc.
The D8 Advance diffractometer from Bruker is equiped with a high temperature camera (up to 1200ºC), as well as a low temperature camera at cryogenic temperatures (LN2).
