The MagSup team was born from the fusion in 2014 of three teams of experimentalists working on condensed matter physics, from fundamental properties to applications. Over the last five years, we have strengthened our ties within the team while the diversity of cultures of the three original groups allowed novel fruitful approaches. Our team is the largest of the Neel Institute, with 25 CNRS and University researchers and more than 10 student and post-docs.
The research activity of the team can be decomposed into four main topics:
Our objective is to understand and to manipulate the fundamental properties, which emerge from microscopic interactions and or from the interplay between several degrees of freedom (charge, spin, orbital, lattice) in a great variety of strongly correlated electrons systems. These are materials such as transition metals oxides, compounds of actinides or rare-earths, or disordered systems. These systems exhibit unconventional properties of magnetism, superconductivity, charge orderings, with several coexisting orders sometimes strongly coupled and/or in competition due to magnetic frustration. Our microscopic understanding of the fundamental states and associated excitations is established in strong connection with theoreticians and allows us, in collaboration with chemists, to foresee and study in depth new systems. Eventually, we simulate and manipulate the functionalities of these materials to create new devices.
We also develop an original instrumentation in the laboratory and use large scale facilities (neutron sources, synchrotron, intense magnetic field), in extreme conditions of magnetic fields, (low) temperature and pressure. The team is perfectly established in its Grenoble environment. It interacts narrowly through experimental developments and joint doctoral and scientific projects, within Institut Néel, but also with the LNCMI, G2Elab, CEA’s IRIG teams and European large scale facilities, ESRF and ILL. We also play an essential role in structuring and animating local, national and international science in organising seminars, conferences and schools, but also in participating in commissions and management positions.

The symmetry of materials has a profound effect on their quantum properties. Recently, the scientific community identified intriguing materials that respect global centrosymmetry (the presence of an inversion centre), but lack an inversion centre on the most important atom, i.e. the rare earth atom (such as cerium or uranium). One major consequence is the presence of a new type of spin-orbit coupling with alternate orientation in the unit cell. As a consequence, new kind of quantum order emerges, such as unconventional superconductivity in CeRh2As2 or new type of order built from entangled electronic states of two Rare earth sites.

You will investigate an important problem of condensed matter physics: the interaction between two quantum states of matter, namely superconductivity and a charge-density wave. This investigation will be performed in a recently discovered family of kagome superconductors, using a newly developed setup of electrical transport under uniaxial stress.
Position type: Post-doc

In this project, we aim to develop a new technology for on-chip spectroscopy using Kinetic Inductance Detectors and a magnetic field (the H-KID projet) [1]. The spectral response of the Kinetic Inductance Detectors will be modified by reducing the superconducting gap using the magnetic field. The aim of the project is to design, build and test at low temperature a spectrometer based on Kinetic Inductance Detectors. The post-doc will focus mainly on low-temperature tests in a 100 mK optical dilution refrigerator. She/he may also be involved in the design and nano-lithography of detectors and/ or in the programming of new readout electronics.

Electron-phonon coupling, one of the possible glues for Cooper pairing which lead to superconductivity, has a smoking gun with the isotope effects on the superconducting transition temperature Tc. The latter is observed in the cuprate high-temperature superconductors, but it is rarely considered and often ignored. We propose to unveil if the effect is present also in superconducting doped oxychloride cuprates, a compound which is very promising to bridge the gap between theory and experiment, because of their simple structure.
