Investigation of structural and magnetic properties of Nd0.7Ba0.3Mn1-xTixO3 (x = 0.05, 0.15 and 0.25) manganites synthesized through a single-step process

Correlation between critical magnetic behavior and griffiths phase in ferromagnetic La0.7Sr0.3Mn1−xFexO3 (x = 0.05) nanoparticle

“…The fit yields q cw = 300.57 K and m eff exp = 5.33 μ B , whereas the theoretical value of m = eff theo 4.67 μ B . The positive value of q cw and the experimental value of the PM moment are larger than its theoretical value to confirm the existence of the FM component within the PM region of the sample [61]. More importantly, the c -T 1 ( ) plot shows a deviation from the CW behavior much below ∼344 K, which is denoted as T G as mentioned earlier [25,26].…”

X-ray diffraction analysis of Cu2+ doped Zn1-xCuxFe2O4 spinel nanoparticles using Williamson-Hall plot method

“…The crystallite size and lattice strain of the NPs of ZCFO ferrites were calculated using modified Scherrer's formula and Williamson-Hall (W-H) method. According to W-H method broadening in the peak due to crystallite size (β d ) and lattice strain (β s ) can be given by the equation: β hkl = β d + β s β hkl = k λ/(dcosθ hkl ) + 4ε tanθ hkl where, λ is the wavelength of Cu Kα X-ray radiation (λ = 1.5406 Å), d is average value of crystallite size, k is a constant equal to 0.89, θ hkl is Bragg's angle, β hkl is the full width at half-maximum corresponding to (hkl) Bragg's peak, and ε is the average value of lattice strain [9][10][11]. Rearranging the above equation gives:…”

“…The average particle size of the sample falls into the range 30-45 nm, which confirms that the synthesized sample is nanocrystalline. The average value of the particle size was estimated considering as many particles as possible from the micrographs using ImageJ software and found to be ~ 40 nm [11]. A histogram for the particle size was plotted to find out the most probable value of particle size by fitting Gaussian curve.…”

The Physical Properties of Submicron and Nano-Grained La0.7Sr0.3MnO3 and Nd0.7Sr0.3MnO3 Synthesised by Sol–Gel and Solid-State Reaction Methods

“…At present, there are several well-established methods, such as solid-state reaction [15][16][17], co-precipitation [18], sol-gel [17,[19][20][21], microemulsion [22], pyrophoric reaction [23][24][25], hydrothermal [26], and combustion [27,28], that have been utilised to synthesise different grain distributions in manganites. The solid-state reaction method is commonly applied to prepare the manganites.…”
