The synthesis and the magnetic properties of Nd2O3-doped Ni–Mn ferrites nanoparticles

Study on magnetic properties of nanocrystalline La-, Nd-, or Gd-substituted Ni–Mn ferrite at low temperatures

“…However, the diffraction peaks in Ni 0.7 Mn 0.3 RE 0.1 Fe 1.9 O 4 ferrites appear to broaden as a result of incorporation of the rare-earth ions. Such results have been reported in the literatures about the spinel ferrites doped with rare-earth ions [19,20] (Fig. 1) During the process, magnetization can be expressed by the equation DM H ¼ DM domain wall displacement þ DM domain wall rotation þ DM paramagnetic magnetization .…”

Cation distribution and Mössbauer spectral studies of Mg0.2Mn0.5Ni0.3InxFe2−xO4 ferrites (x=0.0, 0.05 and 0.10)

“…The variation of lattice constant will lead to the lattice strains, which produce the internal stress [17,18]. Such a stress hinders the growth of grains, so the grain sizes of the samples doped with In 3+ ions are smaller than that of Mg-Mn-Ni ferrite nanocrystal, Table 1.…”

Influence of Nd3+ substitution on structural, electrical and magnetic properties of nanocrystalline nickel ferrites

“…In recent years several researchers have prepared nanosized ferrites by sol-gel method [2,5], emulsion method [6], co-precipitation method [2,7], citrate precursor method [8], tartrate precursor method [9], hydrothermal method [10], reverse micelle technique [11], microemulsions [12], high energy ball milling technique [13] and pulsed wire discharge method [14]. There are many reports in literature on the studies of Ni-Cr [15], Ni-Ge [16], Ni-Zn [17,18], Ni-Al [19], Ni-Cd [20], Ni-Li [21], Ni-Cu [22], Ni-Mg [23] and Ni-Mn [24] ferrites.…”
