Magnetism in the i-$R$-Cd ($R \quad =$ Y, Gd-Tm) binary quasicrystals

ORAL

Abstract

Progress in our understanding of the consequences of aperiodicity for physical phenomena such as the electronic, magnetic, and optical properties has recently seen a surge of activity and new results. A new family of i-$R$-Cd binary magnetic quasicrystals, exhibiting spin-glass-like behavior, and the closely related $R$Cd$_{\mathrm{6}}$ crystalline approximants , which manifest long-range magnetic order at low temperature, offer new opportunities for studies of the impact of aperiodicity on magnetic interactions in compounds that have similar local structures. I will discuss their magnetic behavior, as well as recent x-ray diffraction and elastic magnetic neutron scattering investigations that provide some insight into their structural and magnetic properties.
