Chapter 206 μSR studies of rare-earth and actinide magnetic materials

摘要: Publisher Summary The muon spin rotation/relaxation/resonance (μSR) spectroscopy has become an important tool for probing local static and dynamic magnetic properties. In over two decades a quite substantial body of μSR data been collected from rare-earth actinide materials, the latter, however, mostly restricted to samples containing uranium. is measurement temporal development spatial orientation spins muons, which have implanted in material interest with all initially fixed one direction (complete polarization). can be performed either positive or negative muons. latter behave like heavy electrons will captured into Bohr orbits by atoms sample material. They quickly reach ls ground state, whose orbital radius, comparable nuclear radii. Negative muons thus sense predominantly effects protonic charge distribution result primarily physics. field at site compound is, least part, created dipole moments on neighboring paramagnetic ions.
