Far-infrared reflection and transmission of La1−xCaxMnO3

Ultrasound and Microwave-Assisted Co-precipitation Synthesis of La0.75Sr0.25MnO3 Perovskite Nanoparticles from a New Lanthanum(III) Coordination Polymer Precursor

“…Thus, after calcination, the characteristic bands of OH group disappeared and only strong bands due to the perovskite oxide appeared. In the FT-IR spectrum of the product after calcination, showed the main absorption band around 606 cm −1 corresponding to stretching of the metal-oxygen bond in the perovskite, which involves the internal motion of a change in Mn-O-Mn bond length in MnO 6 octahedral structure [25]. The bands' positions are in good agreement with those reported in the literature [26].…”

Synthesis, structural and ferromagnetic properties of La1−x K x MnO3 (0·0 ≤ x ≤ 0·25) phases by solution combustion method

“…These two bands are related to the environment surrounding the MnO 6 octahedra in the ABO 3 perovskite (Arulraj and Rao 1999;Gao et al 2002). These absorptions disappear when x exceeds 0⋅15, on account of the metallic nature of the oxides ( figures 5(d-f)).…”

Hydrogen Peroxide Decomposition over Nanosized La1–XCaXMnO3 (0 ≤ X ≤ 0.6) Perovskite Oxides

“…The average crystallite size of La 1-X Ca X MnO 3 (X =0.0, 0.2, 0.4, and 0.6) can be determined from the Scherrer equation (D = 0.89 k / B cosh) after Warren's correction for instrumental broadening [19]. In this formula, D is the diameter of the particle, k is the wavelength (for Cu K a , k = 1.5418 Å), and B is equal to (B M 2 -…”
