    Prof. Wolfgang Wernsdorfer 

  • Objective:

    The micro-SQUID facility has a 1010 times better sensitive than a conventional SQUID magnetometer. This magnetometer will be used to study the low-temperature magnetic properties molecular nanomagnets, synthesized in collaboration by chemist groups. Detailed studies of the magnetic anisotropy, the slow relaxation of magnetisation, and the quantum dynamics will be performed in view of molecular spintronics applications.

    • talk both the languages of the physicists and the synthetic chemists 
    • profound experiences in chemical laboratories concerning the general physical characterization techniques (in particular crystallography, SQUID magnetometry, ...)
    • able to interpret the results obtained by physical methods
    • familiar with molecular magnetism, hysteresis properties, quantum tunnelling, etc. 
    • speak English fluently and have good communication skills at conferences
