Effect of neodymium doping on electrical properties and relaxor ferroelectric behavior of YCrO3 nanoparticles

A comprehensive review on the ferroelectric orthochromates: Synthesis, property, and application

“…The conductivity dependences of free-charge and space-charge carriers increase as the doping content increases. Moreover, the relaxer ferroelectric behavior is enhanced with increasing the Nddoping level in YCrO 3 [263].…”

“…(11) Y 1−x Nd x CrO 3 . Nd-doped Y 1−x Nd x CrO 3 (x = 0.0, 0.01, 0.05, and 0.10) nanomaterials were prepared by Sinha et al with the sol-gel method, and the electrical, relaxor ferroelectric, and FM properties were studied [263]. The samples display a semiconductor behavior, and the conductivity increases upon Nd-doping, accompanied by the decrease of the dc activation energy.…”

Crystalline and magnetic structures, magnetization, heat capacity and anisotropic magnetostriction effect in a yttrium-chromium oxide

“…Among the catalysts of ABO 3 -type perovskite oxides (A = La, Y, Nd, or Gd; B = Fe, Mn, Cr, or Co) for the oxidation of 1,2-dichlorobenzene, the YCrO 3 compound was found to be the most active catalyst and was the only one that displayed no loss of its initial activity after several hours on stream [11]. The studies of nanocrystalline (un)doped YCrO 3 materials were reported [22][23][24]. The Nd-doped YCrO 3 nanoparticles display a semiconducting feature and an enhanced dc conductivity as the Nd content increases, following the Dyre's free energy barrier model [24].…”

“…The studies of nanocrystalline (un)doped YCrO 3 materials were reported [22][23][24]. The Nd-doped YCrO 3 nanoparticles display a semiconducting feature and an enhanced dc conductivity as the Nd content increases, following the Dyre's free energy barrier model [24]. The magnetic configuration below T N = 140 K of the YCrO 3 compound was proposed to be a canted antiferromagnetic (AFM) structure with antisymmetric spin superexchanges [25][26][27].…”
