Localised canting models for substituted magnetic oxides

Study of magnetization and crystallization in sputter deposited LiZn ferrite thin films

“…The high field susceptibility seen in our thin films are an order of magnitude higher than those reported by Patton and Liu. 25 Canting can, therefore, not be the reason of high field susceptibility in our thin films. Moreover, we have carried out a similar study in thin films that did not have any zinc in it.…”

“…Patton and Liu 25 have studied high field susceptibility in a bulk LiZn ferrite system. They have observed the high field susceptibility to increase as a function of zinc concentration and to be significant only for zinc concentrations above 0.4.…”

Investigation of iron deficient and manganese doped Ni–Mg nano-ferroxide ceramics

“…In superparamagnetic materials, responsiveness to an applied magnetic field without retaining any magnetism, after removal of the magnetic field is observed. The most probable explanation is that, this is because of the mono-domain character of nanoparticles and absence of inter domain exchange interactions that form the basis of superparamagnetism; a magnetic nanoparticle property [25][26][27]. It was observed that the coercivity first decreases with an increase in Mn content, reaches a minimum at x=0.2 and thereafter increases with Mn content.…”

Localized canting of spins structure in the spinel oxide system: ZnzTizFe2−x−zCrx−zCoO4

“…But the approximation must not be done for the A-site magnetic ions environment to any B-site magnetic ion insofar as this parameter can be very small and have a large statistical probability at the same time. The detail discussion is found elsewhere [19]. In the present neutron diffraction study, the deduced site moments are shown in Table 3.…”

“…Since it was very clearly shown by the neutron diffraction study that the compositions (x ¼ 0:60; 0.65, 0.70) possess the ferrimagnetic ordering of longitudinal components of locally canted spins, an attempt is made to account for the magnetic moments deduced from 10 K neutron diffraction study of all these compositions, using the LCS approach as proposed by Patton and Liu [19]. The LCS model developed by Patton and Liu is applied to the case where A-site magnetic dilution is prominent with no B-site dilution.…”
