Descripción del proyecto
Una nueva tecnología permite obtener imágenes de materiales cuánticos en campos magnéticos de alta intensidad
Las tecnologías avanzadas de microscopia, como el microscopio de efecto túnel, han revolucionado la obtención de imágenes de superficies a nivel atómico. Los átomos individuales pueden ser visualizados en diferentes temperaturas y valores de campo magnético. A diferencia de la temperatura, el campo magnético es un campo vectorial, lo cual significa que su dirección es tan importante como su magnitud en el estudio de los materiales. El equipo del proyecto VectorFieldImaging, financiado con fondos europeos, desarrollará una tecnología rentable que permitirá variar la dirección del campo magnético en los campos magnéticos de alta intensidad disponibles. La tecnología propuesta modificará la orientación de todo el microscopio con respecto al solenoide. Si se logra, la tecnología revolucionará los estudios de los materiales a nanoescala, al ofrecer nuevos conocimientos sobre muchos fenómenos cuánticos.
Objetivo
The invention of the scanning tunneling microscope (STM) and of other similar devices was a revolution for research at atomic scale. Many companies offer microscopes which can be used to study materials at atomic scale as a function of temperature or magnetic field. However, unlike temperature, the magnetic field is a vector quantity. The direction of the magnetic field vector is as important as its magnitude when it comes to study properties of materials at atomic scale. The only solution available today to vary the vector of the magnetic field is to build a set of three separate solenoids, with which one can generate separately the three components of the magnetic field vector. However, this unavoidably implies a significant reduction of the magnitude of the largest vectorial fields that one can obtain, typically at most 1-2 T. The EU proposal VectorFieldImaging will overcome this challenge by developing new technology to modify the orientation of the entire microscope with respect to the solenoid. This will provide a significantly less-costly solution that will allow the direction of the magnetic field to be varied at the highest available magnetic fields, opening the door to the microscopic studies of many quantum phenomena. Specifically, the project will focus on a proof of concept by establishing technical feasibility, usability and commercialization of prototypes that allow turning a STM inside a high magnetic field solenoid tested in an operational environment by end users. If successful, this technology will make a real breakthrough in the area of quantum materials by allowing visualization by means of scanning probes at very high vectorial magnetic fields.
