Effect of sintering temperature on structural, magnetic, magnetocaloric and critical behaviors of Ni-Cd-Zn ferrites prepared using sol-gel method

Sintering Temperature Effects on Structural, Magnetic, Magnetocaloric and Critical Properties of Nd0.67Pb0.33Mn0.9Al0.1O3 Manganites

“…In particular, by comparing the values found for our compounds, we can notice that the value of β decreases however the γ and δ values increase as the sintering temperature increases. A similar behavior was observed in other works [37,38].…”

Structural, Dielectric and Electrical Properties of Sol-Gel Auto-Combustion Technic of CuFeCr0.5Ni0.5O4 Ferrite

“…13. Therefore, this variation confirms the non-Debye dielectric behavior of the Cr0.5Ni0.5FeCuO4 ferrite [29]. N. Sivakumar et al [80] considered that the increase of β1 and β2 values with sintering temperature was linked to the rise of grain size on fabrication steps.…”

“…The estimated value of the average crystallite size is presented in Table 1. The X-ray density of our sample was calculated according to the following equation [29][30][31][32][33][34]…”

Magnetocaloric Effect, Dielectric Relaxor Behavior, and Evidence for Direct Magnetodielectric Behavior in Ni0.6Zn0.4Al0.5Fe1.5O4 Ceramics for High-Temperature Applications

“…Among all these technology applications, magnetic refrigeration application is one of the most promising ones. A large study has been dedicated to ceramic ferrite in the magnetic refrigeration technology (MCE). , It is a cost-effective and environment friendly technology based on the concept of the magnetocaloric effect (MCE) alternative to the conventional gas compression/expansion system. , The MCE is defined as a magneto-thermodynamic phenomenon in which a temperature change in the magnetic material occurs as a result of varying the magnetic field. − MCE is defined as the tendency of a magnetic system to cool down or heat up through a magnetization–demagnetization process . The applied significance of the MCE is easily evaluated and successfully used to reach ultralow temperatures in a research environment .…”
