Abstract

Yttrium iron garnet (Y₃Fe₅O₁₂ or YIG), an amorphizable ferrimagnetic insulator, is probably the best studied material with respect to track formation and damage morphology. This paper presents first scanning force microscopy (SFM) of surface damage induced by energetic C₆₀ clusters. YIG single crystals were irradiated at normal incidence with 30-MeV C₆₀ cluster ions (kinetic energy ∼0.04 MeV/u) provided by the tandem accelerator of the Institute of Nuclear Physics in Orsay (IPNO). The SFM topographic images show nano-protrusions on the YIG surface; where each hillock is generated by one C₆₀ cluster. The role of stopping power and deposited energy density is discussed in terms of dimensional analysis of the nanostructures. Hillocks created by C₆₀ clusters are compared with those produced by monatomic ions.
