Structural and magnetic properties of (In1−xFex)2O3 (0.0⩽x⩽0.25) system: Prepared by gel combustion method

Abstract

Abstract:(In 1-x Fe x ) 2 O 3 polycrystalline samples with x = (0. 0, 0.05, 0.10, 0.15, 0.20 and 0.25) have been synthesized by a gel combustion method. Reitveld refinement analysis of X ray diffraction data indicated the formation of single phase cubic bixbyite structure without any parasitic phases. This observation is further confirmed by high resolution transmission electron microscopy (HRTEM) imaging, and indexing of the selected-area electron diffraction (SAED) patterns, X-ray Absorption Spectroscopy (XAS) and Raman Spectroscopy. DC Magnetization studies as a function of temperature and field indicate that they are ferromagnetic with Curie temperature (T C ) well above room temperature. a Corresponding author Email: ikgopal@barc.gov.in

Room temperature ferromagnetism in Th1−xFexO2−δ (x=0.0, 0.05, 0.10, 0.15, 0.20 and 0.25) nanoparticles

“…Yoo et al [11], have shown that Fe doped In 2 O 3 co-doped with Cu (Fe up to 20 at.%) is one of the oxide systems that shows promising results as a potential candidate for DMS. Recently, we were able to induce ferromagnetism in Fe doped In 2 O 3 (Fe concentration up to 20 at.%) without introducing Cu as the additional dopant [21].…”

Temperature dependence of magnetoresistance in Co/ITO multilayers

“…Much attention has been paid to ITO and indium oxide recently. Room temperature ferromagnetism has been found in various transition-metal doped ITO, indium oxide films [11][12][13][14] and powers [15][16][17]. Effective spin injection has been realized in CoFe/ITO system [18].…”

Alkali tuning phases and morphologies of Ni2+ doped In2O3 nanocrystals

“…As a new kind of DMSs, 3d transition-metal doped indium oxide (TM-In 2 O 3 ) has been attracting increasing attentions for In 2 O 3 is not only widely applied in semiconductor and catalyst industries [2,3], but has also high solubility of TM ions [4]. Traditionally, TM doped or co-doped In 2 O 3 is usually prepared by physical methods such as laser ablation, pulsed laser deposition, solid state synthesis and combustion method; moreover, the samples are mainly focused on bulk, polycrystalline or thin film materials [5][6][7][8][9][10][11][12][13]. However, the reports on TM doped or co-doped In 2 O 3 nanomaterials are quite sparse.…”
