Lay Summary (French)

Lead
Dans ce projet, nous visons à l'acquisition d'un aimant supraconducteur sans liquides cryogeniques avec insert de température variable pour effectuer des expériences dans le domaine de champ magnétique entre 0 et 7 T et dans la gamme de température de 0,3 à 300 K. L'instrument proposé est spécifiquement conçu pour des expériences de spectroscopie de résonance magnétique (résonance de spin électronique (RSE), résonance magnétique nucléaire (RMN), résonance ferromagnétique (RFM)). L'instrument proposé permettra d'étudier des sujets scientifiques qui ne peuvent pas être traitées avec l'instrumentation actuellement disponibles dans les laboratoires partenaires du projet ni dans leur établissement d'origine. Ces expériences nécessitent un champ magnétique très stable et uniforme dans l'espace, avec un ajustement de la résolution élevée de la valeur du champ magnétique, combiné avec une large gamme de température allant de la température ambiante jusqu'à des températures sous-Kelvin.

n this project we aim at the acquisition of a cryofree superconducting magnet with variable temperature insert to perform experiments in the magnetic field range from 0 to 7 T and in the temperature range from 0.3 to 300 K. The proposed instrument is specifically conceived for magnetic resonance spectroscopy experiments (i.e., electron spin resonance (ESR), nuclear magnetic resonance (NMR), and ferromagnetic resonance (FMR)). The proposed instrument will allow to investigate scientific topics that cannot be addressed with the instrumentation currently available in project partner’s laboratories nor in their home institution. Such experiments requires a very stable and spatially uniform magnetic field, with a high resolution adjustment of the magnetic field value, combined with a wide temperature range from room temperature down to sub-Kelvin temperatures.

Abstract

In this project proposal we aim at the acquisition of a cryofree superconducting magnet with varia-ble temperature insert to perform experiments in the magnetic field range from 0 to 7 T and in the temperature range from 0.3 to 300 K. The proposed instrument is specifically conceived for magnet-ic resonance spectroscopy experiments (i.e., electron spin resonance (ESR), nuclear magnetic reso-nance (NMR), and ferromagnetic resonance (FMR)). The proposed instrument will allow to investi-gate scientific topics that cannot be addressed with the instrumentation currently available in pro-ject partner’s laboratories nor in their home institution. Such experiments requires a very stable and spatially uniform magnetic field, with a high resolution adjustment of the magnetic field value, combined with a wide temperature range from room temperature down to sub-Kelvin temperatures. The instrument will allow the project partners to:(1) study the limits of detection in inductive ESR by means of the single-chip microwave oscillators and perform ESR experiments hitherto beyond the sensitivity limitations of state-of-the-art induc-tive systems, (2) study the behavior of single-chip microwave LC-oscillators in the “quantum condi-tion” limit, which might allow to observe, for the first time, “macroscopic artificial atom” like proper-ties of an LC-oscillator, (3) study quantum quench phenomena by NMR spectroscopy, (i.e. sudden changes in the system Hamiltonian giving rise to non-equilibrium evolution of a quantum many-body state), (4) study unconventional cavity microwave-magneto-mechanics couplings, and (5) study small samples of biological relevance, such as single crystals of beta-hematin. In the research plan, we describe each of these subprojects in some details. Most of these subpro-jects are related to currently running projects, others are exploratory investigations towards new research directions.
