“…Scanning Electron Microscope (SEM) result shows that the material consisted of fine grains with randomly oriented equiaxed grain morphology [8]. The compositional purity of this sample has been confirmed by Energy Dispersive X-ray (EDX) analysis, and there is no impurities can be detected [9]. Figure 1 shows the temperature dependence of magnetization of polycrystalline La0.7Ba0.3MnO3 at 100 Oe under zero magnetic cooling (ZFC).…”

“…Meanwhile, SE interaction caused the material has paramagnetic behavior. The largest mobility is found in the ferromagnetic domain around x = 0.3 [9]. SE interaction deduced in La0.7Ba0.3MnO3 at below Tc is explained by Goodenough-Kanamori rules for d 3 -d 3 overlap [11].…”

“…On the other hand, the paramagnetic behavior is when magnetization value of the material increases linearly with increasing magnetic field [3]. Magnetic transition phenomenon occurred when parental compound LaMnO3 doped with a divalent ion such as Ba 2+ , Ca 2+ , Sr 2+ , etc [9]. Parental compound LaMnO3 has paramagnetic behavior but divalent ion doping in La site caused this compound has a ratio of Mn 3+ and Mn 4+ [10].…”

Effect of addition of butyl benzyl phthalate plasticizer and zinc oxide nanoparticles on mechanical properties of cellulose acetate butyrate/organoclay biocomposite AIP Conference Proceedings 1862, 030059 (2017) Abstract. In this paper, we report on the observation of magnetic properties of polycrystalline La0.7Ba0.3MnO3 and its magnetocaloric properties. This material has been intensively studied in the recent years because this material has a high potential application. The magnetic measurement was performed by using Vibrating Sample Magnetometer (VSM) in the range of temperature between 300-400 K under influencing magnetic field until 20 kOe. As inferred from the minimum value obtained from the derivatives of temperature dependence magnetization data, Curie temperature (Tc) of this material is 332 K. By using magnetic field versus magnetization data from isothermal condition measurement and thermodynamics Maxwell relation, the magnetic entropy change (ΔSM) of this material is -3.08 J.kg -1 K -1 . This value is higher than the solid state one from the previous study. It might occur due to physical properties of this material improved since preparation material via a sol-gel method could obtain fine particle and homogeneous distribution of particle size.
