Substitution effects on frustrated magnetism of chromite spinel ACr2O4 (A = Zn, Cd)

Effect of Cd2+ Substitution on Structural–Magnetic and Dielectric Properties of Ni–Cu–Zn Spinel Ferrite Nanomaterials by Sol–Gel

“…In a Bohr magnetron, the trend of the magnetic moment for each formula unit is the same as the saturation magnetization intensity. The same phenomenon was discovered by Kaur, Harpreet, et al using non-magnetic ions in Cd-doped CoFe 2 O 4 [25]. The coercivity of the samples decreases as the Cd 2+ increases, as can be observed from the lower right inset of Figure 12.…”

“…Metal ions occupy tetrahedral (A) or octahedral (B) positions, with oxygen ions as the backbone [ 4 , 23 , 24 ]. The variation of different ions in the tetrahedral or octahedral positions can alter the structural, electrical, magnetic, and catalytic properties of spinel-type ferrite nanomaterials [ 17 , 25 , 26 ]. Rahmayeni et al [ 27 ] synthesized CuFe 2 O 4 /activated carbon (CuFe/AC) composites from activated carbon extracted from oil palm waste using green shellfish leaf extract as a biocovering agent, which showed a photocatalytic degradation activity up to 92.10% of rhodamine B under 2 h of light.…”

Photocatalytic properties of nanosized zinc ferrite and zinc chromite

“…One of the rapidly developing areas of oxide spinel chemical technology is the development of nanostructured material synthesis methods. Ceramics is considered to be the traditional method of spinel synthesis, during which high-temperature firing of the initial precursors, customarily an oxide, is used [25,26]. Sometimes, to reduce synthesis temperature or duration, a combination of solid-state and additional methods such as microwave irradiation [27] and hydrothermal exposure [28] is used.…”
