Influence of rare earth (Nd+3) doping on structural and magnetic properties of nanocrystalline manganese-zinc ferrite

Influence of neodymium substitution on structural, magnetic and spectroscopic properties of Ni–Zn–Al nano-ferrites

“…Having a closer look at the images, it can be observed that not regular spherical shaped and nanosize of the grains. These results are analogous to other researcher's work made previously such as P. P. Naik et al who reported in their publication 12 that "large agglomerates of many particles are formed". Furthermore, the surface morphology exposes distribution of small grains at the grain boundaries, which is the unique mark of Ni-Zn ferrites.…”

“…37 Moreover, the vibration band (n 1 ) is widened and shied towards the higher wavenumber region with an increased Nd 3+ doping level (see Table 3). Same behavior was observed in Nd doped Mn 0.6 Zn 0.4 Fe 2 O 4 reported by Naik et al 12 This shiing is x ¼ 0.0 3. The force constants of the A and B sites increase with increasing the doping level x.…”

Magnetic, structural and cation distribution studies on $\mathrm{FeO}\cdot\mathrm{Fe}_{(2-x)}\mathrm{Nd}_{x} \mathrm{O_{3}}$ (x = 0.00, 0.02, 0.04, 0.06 and 0.1) nanoparticles

“…7-(b)) are fitted with a Langevin function (Eq. ( 16)), weighted with the particle-size distribution function (PDF) [58,59]: (16) where M(H,T) is the magnetization of the magnetic nanoparticles at the temperature T (300 K) , N sc is a scaling constant, M S represents the saturation magnetization of the magnetic nanoparticles and [59]. The quantity V V , stands for the volume-weighted average volume of the nanoparticles given by [52].…”

“…Aslam and co-workers performed a co-doping of Nd 3+ and Pr 3+ on lithium nanoferrite and reported the effects on the magnetic and structural properties of the system [15]. The effect of Nd +3 doping on Mn-Zn ferrite was reported in the literature [16,17], and an enhancement of the saturation magnetization, due to the new cation distribution imposed by Nd doping was reported.…”

Modifying the Soft Magnetic Properties of Mn-Zn Ferrites by Ce2O3-Doping and Sintering Temperature Optimization

“…Recently, rare earth (RE) elements have received much attention from ferrite industries. 6,7 Different kinds of RE elements, such as gadolinium (Gd), 8 dysprosium (Dy), 9,10 neodymium (Nd), 11 samarium (Sm), [12][13][14][15][16] lanthanum (La), 17 terbium (Tb), 10,18,19 cerium (Ce), 18,[20][21][22] etc., have been introduced into different types of ferrites. The obtained results reveal that, by introducing a small amount of RE 2 O 3 to substitute Fe 2 O 3 , modifications of both the structure and the magnetic properties can be obtained.…”
