Abstract
The results of investigations of magnetic properties of ternary layered TlInS2 and TlGaSe2 lferroelectric crystals implanted with 40 keV Co+ ions at the fluency of 1.0 x 1017 ion cm-2 are presented. It has been revealed that high-fluence implantation with Co ions results in metal nanoparticle formation in the near-surface irradiated region. The calculations of Co concentration profiles and SEM studies show that the metal nanoparticles are located under the surface at the depth of about 20 nm, and they originate the irregular-shaped bumps on the surface. The Co-implanted samples exhibited superparamagnetic behaviour at high temperatures and ferromagnetic state at temperatures lower than Tb, where Tb is a "blocking temperature" of superparamagnetic nanoparticles. It has been suggested that the observed phenomena can be discussed on the basis of strong magnetic dipolar interaction between Co nanoparticles inside the granular composite film formed as a result of implantation.
