title: Magnetism in icosahedral quasicrystals: current status and open questions.
abstract: Progress in our understanding of the magnetic properties ofR-containing icosahedral quasicrystals (R= rare earth element) from over 20 years of experimental effort is reviewed. This includes the much studiedR-Mg-Zn andR-Mg-Cd ternary systems, as well as several magnetic quasicrystals that have been discovered and investigated more recently including Sc-Fe-Zn,R-Ag-In, Yb-Au-Al, the recently synthesizedR-Cd binary quasicrystals, and their periodic approximants. In many ways, the magnetic properties among these quasicrystals are very similar. However, differences are observed that suggest new experiments and promising directions for future research.
