Structural, magnetic and semiconducting properties of Fe doped SrSnO3

Room-temperature ferromagnetism and oxygen pressure-dependent optical, ferromagnetic properties in SrSn0.5Co0.5O3 thin films

“…The hysteresis loops were observed at all four investigated temperatures and testified the room-temperature ferromagnetism of the SSCO film. Especially, the magnetic properties of the film at room temperature were fairly good compared with previous reports [7,[20][21][22], and exhibited the saturated magnetization (M s ) of 12 emu cm −3 , the remnant magnetization (M r ) of 4.3 emu cm −3 , the coercive field (H c ) of 316 Oe and saturated field (H s ) of 5000 Oe. In view of the relatively high M r /M s ratio (300 K: 0.358; 100 K: 0.57) and H c /H s ratio (300 K: 0.12; 100 K: 0.40), the film was more close to the hard magnetic material.…”

“…The optical band gap of 2.36 eV was realized in epitaxial SrSn 1−x Fe x O 3 films on MgO [18] and 2.44 eV in epitaxial SrSn 1−x Co x O 3 films on SrTiO 3 (STO) [19]. There is no report on the ferromagnetism of thin films up to now, though weak ferromagnetism was reported in bulk SrSnO 3 doped by Fe or Cr [20,21].…”

Fe(iii) induced structural, optical, and dielectric behavior of cetyltrimethyl ammonium bromide stabilized strontium stannate nanoparticles synthesized by a facile wet chemistry route

“…Among the perovskite, alkaline earth stannates (MSnO 3 , M ¼ Mg, Ca, Sr, Ba) form a special class of materials due to their structural, optical, dielectric properties and photovoltaic behavior. [1][2][3][4] These properties have been tailored by substituting the host cations by transition metal ions. 5,6 The alkaline earth stannates fall in the class of ferroelectric oxides that are used in the fabrication of electronic components in various electronic devices, such as capacitors, thermistors and transducers, as they have a low temperature coefficient of capacitance.…”

Effect of Fe doping on the structural, morphological, optical, magnetic and dielectric properties of BaSnO3

“…Also, the observed magnetic moments can be due to F-centre exchange (FCE) mechanism of Fe-V0-Fe in which direct ferromagnetic coupling of metal ions takes place through an oxygen vacancy [50]. Pratiba et al, reported the origin of ferromagnetic behavior in Fe doped BaSnO3 is through electrons trapped at defects such as the oxygen vacancies (F center) form a bound magnetic polaron [51]. Coey et al, [52] reported the bound magnetic polaron (BMP) model for the observed ferromagnetism in Fe doped CaSnO3 and for magnetic ordering in insulating systems.…”
