“…Such magnetic properties also play an essential role in the application within, for example, magnetic resonance imaging, data storage, and drug delivery systems. 4 , 8 …”

“…The well-established spinel magnesium oxide family (Mg M 2 O 4 where M is a transition metal atom) has been the subject of interest within a broad scope of research as well as applications, for example, catalysts, humidity sensors, or microwave devices. − Recently, increased attention has been drawn to a series of Mg materials, following the development of high-energy-density rechargeable magnesium batteries. − However, spinel magnesium oxides also have many interesting fundamental materials properties, including diverse magnetic spin orders. This class of materials displays paramagnetism, ferrimagnetism, superparamagnetism, and spin-glass behavior.…”

Cation Distributions and Magnetic Properties of Ferrispinel MgFeMnO4

“…The long-established spinel magnesium oxide family (MgM 2 O 4 where M is a transition metal atom) has been the subject of interest in diverse research fields, e.g., catalyst, humidity sensor or microwave devices. [1][2][3][4] Recently, much attention has been drawn to series of Mg materials, following the development of high-energy-density rechargeable magnesium batteries. [5][6][7] The main fundamental interest of studying the spinel magnesium oxide is that various magnetic properties like paramagnetism, ferrimagnetism, superparamagnetism and spin glass behaviour have been reported for these classes of materials.…”

“…These magnetic properties play an essential role in the application of magnetic resonance imaging, data storage and drugs delivery. 4,8 Spinels have the general formula AB 2 O 4 , and most of them are reported to have a cubic structure with space group F d3m. The structure consists of tetrahedrally coordinated A site cations at 8a (1/8, 1/8, 1/8), octahedrally coordinated B sites cations at 16d (1/2, 1/2, 1/2), and O atoms on the body diagonals of a cube at 32e (u, u, u), where u is approximately 1/4.…”
