Effect of Fe doping on the magnetic properties of PbPdO2 nanograin film fabricated by sol-gel method

Lead palladium titanate: A room-temperature multiferroic

“…The character of this phase is however very different from that observed in the perovskite samples, with a very small coercivity (~ 50 Oe) and a much higher saturated moment ( Figure S4, Supplemental Material [25]). It is known that when doped with magnetic metal ions, such as iron, [39] copper or cobalt [38], that PbPdO 2 can become ferromagnetic even at room temperature, and it is likely that this is the origin of the ferromagnetic signal in the PbPdO 2 measured here. While the significantly higher moment of PbPdO 2 means that only a small amount of this impurity phase, if similarly doped, might make measureable ferromagnetic contributions to the signals observed for 10% and 30% Pd doped samples, the very different character of the ferromagnetic signal in both cases confirms that the ferromagnetism observed in the Pd-doped PT samples is intrinsic to those materials.…”

Effects of V and Gd doping on novel positive colossal electroresistance and quantum transport in PbPdO2 thin films with (002) preferred orientation

“…31 Meanwhile, the average size of PbPd 0.9 V 0.1 O 2 and PbPd 0.9 Gd 0.1 O 2 thin films prepared by PLD technology is larger than those prepared by sol–gel spin coating. 10,38,39 Figs. S1(a) and (b) (ESI†) show the EDS elemental mappings of PbPd 0.9 V 0.1 O 2 and PbPd 0.9 Gd 0.1 O 2 thin films, respectively.…”

Strain Engineered Band Gaps and Electronic Properties in PbPdO2 and PbPd0.75Co0.25O2 Slabs

“…It was found that Pd–O hybridization would efficiently mediate the magnetic coupling among Co atoms [ 11 ]. The ferromagnetism and paramagnetism were found to coexist in the Fe–doped PbPdO 2 , and the bound magnetic polaron model was used to account for the ferromagnetism origin [ 12 ]. Based on the measured electronic structures, Pb(Pd 0.9 T 0.1 )O 2 (T = Mn, Co) oxides were found to be the small-gap semiconductors [ 13 ].…”
