Stima dei siti e degli accoppiamenti del muone in materiali magnetici e superconduttori: verso una simulazione automatizzata

First, the theoretical quantum mechanical approach for simulating the time dependent muon spin polarization is described together with its implementation in the open-source, UNDI software package. In particular, the computationally fast and efficient method by Celio is described. Also within this approach, the effects of the electric quadrupolar interactions relevant to accurately capture the physical properties for nuclei with large moment are incorporated. The approach is demonstrated for LiF, Cu, MnSi and utilized to study muon sites and magnetic properties in these compounds.
