Research Projet
Research project :
Magnetic materials play an important role in information storage technology, communication devices, spintronic, quantum computing, medical equipment. The requirements for these applications include scalability and high density, which necessarily means small size, faster data storage or transfer, higher output signals, low power consumption, low cost and reproducible control of the magnetic states.
Single-molecule magnets (SMM) are molecules that display magnetic hysteresis and slow relaxation of their magnetization of purely molecular origin. The molecular nature of SMM leads to unique attribute of quantum magnetism that may allow information to be stored with much higher densities, and to be processed at unprecedented speed.
This study aims at creating advanced 1D molecular magnets by confining Single Molecular Magnets (SMMs) into 1D nanostructures, leading to single chain magnets (SCM@CNT) that exhibit better controlled and addressable magnetic properties. Single-walled carbon nanotubes (CNT) act as chemically and thermally inert nano-containers to realize 1D molecular arrangements that are not possible in free-space and to control cooperative phenomenon to favor strong inter and intramolecular exchange and magnetic anisotropy. Tunable electrical conductivity of CNT will further make the 1D SCMs electrically accessible through magnetoconductance.
The hybrid system physical properties will be probed as a function of the CNT diameter and the molecular structure of the SMM. Raman spectroscopy will be used to probe CNT and SCM@CNT to investigate the physical interactions taking place between the confined SMM and the CNT. Photoluminescence experiments will be also carried out.
Application date:
from now and until selection of the candidate
Starting date : February 2025 Internship duration : 5-6 months
Profile:
This project is suitable for a student with a solid background in photonics, optics or fundamental physics. No prior knowledge of carbon nanotube science is required. The Master 2 internship and then the thesis involve extensive experimental work in sample preparation and the use of free-space optical facilities, so skills in experimental work are mandatory. A strong taste for interdisciplinary research and learning new skills is also essential.
Additional information:
Length of the internship: 2-3 months
Starting date: flexible, to be defined with the candidate
