High-temperature ferromagnetism of Cu-doped PbPdO2 nanograin films

Effects of Mn doping on electronic and quantum transport in PbPdO2 thin films

“…For example, Cu doping enhance the resistivity and thermoelectric power of the material; Co doping decreases the mobility of the material carrier; Zn doping not only reduces the resistivity of the material, but also makes the sample diamagnetic, and so on. [3][4][5][6][7][8][9][10][11][16][17] Manganese-doped semiconductors show a variety of magnetic properties, [18][19][20] including paramagnetism (PM), antiferromagnetism (AFM), ferromagnetism (FM) and spin glass states, which other elemental doping do not have. Firstreported Mn-doped PbPdO 2 in 2011 was synthesised by Lee et al, in which Mn-doped PbPdO 2 pellets were obtained by solid phase reaction and their magnetic properties were studied in detail.…”

“…First-reported Mn-doped PbPdO 2 in 2011 was synthesised by Lee et al , in which Mn-doped PbPdO 2 pellets were obtained by solid phase reaction and their magnetic properties were studied in detail. 21 In 2014, Kim et al followed the same method to prepare Mn and Co-doped PbPdO 2 pellets, 7 and the valence states and electronic structures of Mn and Co were revealed by soft X-ray absorption spectroscopy and photoelectron emission spectroscopy. In 2017, Tang et al prepared Mn-doped PbPdO 2 thin films by sol–gel spin coating, and studied the valence state of the elements and magnetism.…”

“…The intriguing physical properties attracted a bunch of researchers, who have experimentally studied a spectrum of metal cation doping in PbPdO 2 thin lms, including Mn, Fe, Co, V, Gd, Cu, Zn and Li. [3][4][5][6][7][8][9][10] Additionally, Jia et al also studied the Co-F co-doping effects of PbPdO 2 and discussed the inuence of anion doping on PbPdO 2 in detail. 11 In addition, various properties of PbPdO 2 have been studied, such as the effects of nanograin size and strain engineering, strong spin-orbit coupling based on magnetic properties, and multi-magnetic coexistence based on carrier-mediated mechanisms.…”
