Quantum Nanomagnetism

Materials Science Seminar
Javier Tejada, University of Barcelona
March 25, 2013 11:00AM to 12:00PM
Building 223, Room S105
In this talk I will discuss some of our most important results in quantum nanomagnets in the last twenty years. I will start with the tunnelling of the magnetic moment in single domain particles, then I will move to molecular magnets to explain both resonant spin tunnelling and quantum magnetic deflagration/detonation and I will finish discussing the quantum phenomena recently observed in vortices of two dimensional disks and type I superconductors. Probably the most important question to answer now in the cases presented in this talk refers to the possibility to detect both coherent phonons and photons from the demagnetization process of molecular magnets.
