Properties of Mn-Implanted BaTiO[sub 3], SrTiO[sub 3], and KTaO[sub 3]

Abstract

Mn ion implantation into single-crystal or was investigated for its effects on the magnetic properties of these materials. Following annealing at 700°C, the Mn implantation was found to induce ferromagnetic behavior for most of the concentration range investigated. For Mn implantation produced magnetic ordering temperatures near 300 K with coercivities The magnetization/temperature plots showed a non-Brillouin-shaped curve. No secondary phases were detected by high resolution X-ray diffraction. The results are consistent with theoretical predictions for transition metal doping of The same basic trends were observed for both and with the exception that at high Mn concentrations the was no longer ferromagnetic. © 2002 The Electrochemical Society.
