Structural, optical and dielectric properties of Cu_1.5Mn_1.5O₄ spinel nanoparticles

Abstract

In this study, a Cu1.5Mn1.5O4 spinel was successfully synthesized by a sol–gel method at 500 °C for 5 h and characterized by different techniques.

Structural, morphological, and electrical properties of silver-substituted ZnAl2O4nanoparticles

“…It is worth noting that the concept of porosity ( P ), as well as the number of cell units ( N ), proves that the uniform particle size distribution is well agglomerated and almost homogeneous over the entire surface of the samples. 32 …”

“…Then, the link lengths between the spinel structure sites ( L A–A , L B–B , and L A–B ) were deduced using Standely's equations: 32 …”

“…In the same contest, the number of unit cells ( N ) of the crystals (for x = 0.05 and x = 0.1) was calculated using the following formula: 32 where V is the volume of the unit cell.…”

Investigation of optical and electrical properties of the semiconducting α-KZnPO4 compound

“…At the low frequency region below the maximum peak , a pure conduction process takes place. 49 The charge carriers drift to long distances. However, at the high frequency region above the maximum peak ; the carriers are spatially constrained to move freely only within their potential wells over short distances.…”

Study of physical properties of a ferrimagnetic spinel Cu1.5Mn1.5O4: spin dynamics, magnetocaloric effect and critical behavior

“…Cu 1.5 Mn 1.5 O 4 compound were synthesized by the sol–gel method described in our previous study. 39 Low-field ac-susceptibility measurements were made at various frequencies in a temperature range of 20 to 122 K. Magnetic measurements were recorded using a SQUID magnetometer. The magnetization measurements were carried out according to the zero field cooling (ZFC) and field cooling (FC) protocols under 500 Oe and in a temperature range of 20 to 122 K. The isothermal magnetization M ( T , H ) was recorded for different temperatures under a magnetic field up to 5 T.…”
