Graphical abstract: - Highlights: • The results of investigations of magnetic properties of Fe implanted SrTiO{sub 3} are presented. • The measurements of the temperature dependence of the magnetization were performed. • Ferromagnetic hysteresis loops in Fe implanted SrTiO{sub 3} were observed at low temperatures. • Superparamagnetic behavior of the samples at high temperatures was revealed. • It was shown that the magnetization of the samples depends on the fluency of implantation. - Abstract: The results of investigations of magnetic properties of SrTiO{sub 3} perovskite crystal implanted with 40 keV Fe ions at the fluencies between 0.5 × 10{sup 17} and 1.5 × 10{sup 17} ion/cm{sup 2} are presented. It has been revealed that high-fluency implantation with Fe ions results in the formation of a granular metal particulate composite in the irradiated near-surface layer of SrTiO{sub 3} substrate, which exhibits remarkable ferromagnetic behavior. The measurements of the temperature dependence of the magnetic moment showed that the samples exhibit blocking temperature at about 350 K, above which a superparamagnetic behavior has been observed. Ferromagnetic ordering and magnetic hysteresis loops were observed in Fe implanted SrTiO{sub 3} at the temperatures lower than 350 K. It has been shown that the magnetization of the ferromagnetic state depends on the fluency of implantation.
