Tuning the Magnetic Behavior of BaBiO3 Nanoparticles by Pb Doping
Over the last few years, researchers have been seeking novel oxide materials with room-temperature ferromagnetic properties for use in spintronics devices. In a recent work, we have reported room temperature ferromagnetic correlations in BaBiO3 nanoparticles which is non-magnetic in its bulk form. Here we have conducted a systematic study of the magnetic behavior by controlled Pb doping. We observe an increase in magnetic saturation for small Pb doping concentration (~ 1%), this is believed to be due to the strain magnetism induced by doping. Upon further increase in the doping concentration, the ferromagnetic behavior has been found diminished in a controlled manner, which indicates the dominance of non-magnetic ion distribution over strain magnetism.
期刊介绍：
The Journal of Superconductivity and Novel Magnetism serves as the international forum for the most current research and ideas in these fields. This highly acclaimed journal publishes peer-reviewed original papers, conference proceedings and invited review articles that examine all aspects of the science and technology of superconductivity, including new materials, new mechanisms, basic and technological properties, new phenomena, and small- and large-scale applications. Novel magnetism, which is expanding rapidly, is also featured in the journal. The journal focuses on such areas as spintronics, magnetic semiconductors, properties of magnetic multilayers, magnetoresistive materials and structures, magnetic oxides, etc. Novel superconducting and magnetic materials are complex compounds, and the journal publishes articles related to all aspects their study, such as sample preparation, spectroscopy and transport properties as well as various applications.
