“…The sol-gel method is widely used for producing bulk perovskite manganite compounds due to its cost-effectiveness, ease of synthesis, and ability to produce homogeneous samples, as well as for allowing adjustments in transition temperatures through various element doping rates. The hydrothermal synthesis method is frequently used in the literature for the production of LBMO and BMO perovskite nanorods or nanocrystals [14]. However, it is reported that this synthesis method suffers from limitations, particularly in controlling particle size and shape, as well as achieving a homogeneous distribution due to the emergence of undesirable impurities during production [15]− [18].…”

This study investigated the effect of barium (Ba) substitution for lanthanum (La) on the magnetic properties of the half-doped perovskite manganite compound La0.5Ba0.5MnO3 (LBMO). The LBMO sample was prepared via the sol-gel method and sintered in air at 1000°C for 24 hours. Scanning electron microscopy (SEM)-energy dispersive X-ray spectroscopy (EDS) analysis revealed random formation of BaMnO3 nanorods on the LBMO surface. The LBMO perovskite exhibited a particle size distribution of approximately 60 nm, while the BaMnO3 nanorods possessed widths ranging from 100-250 nm and lengths between 5-20 μm. X-ray diffraction (XRD) analysis found that the main perovskite compound (LBMO) exhibits a cubic crystal structure (a = 3.9108 Å), while the nanorods (BaMnO3) possess a hexagonal crystal structure (a = 5.6454 Å, c = 4.8224 Å). The Curie temperature (TC) was determined to be approximately 330 K, close to room temperature, zero field cooling (ZFC) and field cooling (FC) curves to elucidate the magnetic properties. Furthermore, magnetization measurements yielded a magnetic entropy change (-ΔSM) of 0.62 J/kgK at 1 T and 2.25 J/kgK at 6 T.

Understanding the microstructure of materials and their impact on performance is crucial for new electronic devices design. The strong interaction between multiple degrees of freedom (spin, orbit, charge, and lattice) within perovskite type oxides can generate rich electron phase diagrams. The microscopic modulation of manganese ions electron states in rare earth manganate perovskites is the root of many novel macroscopic quantum behaviors, such as giant magnetoresistance phenomenon. For ABO3 type perovskites, the differences of radii and valence states of A‐site ions are used to regulate the coexistence of B site manganese multivalent states (Mn3+, Mn4+, Mn5+), and its ordered structure in the metastable state will create a new combination of electronic states. The ordered arrangement of the multi‐dimensional space of electronic states can induce unique transport properties. Therefore, the preparation of manganate perovskites will provide strong chemical support to construct new generation quantum devices. This review summarizes the challenges and difficulties on constructing trivalent coexisting metastable phase in manganate perovskites through disproportionation reactions, and discusses the status and potential of designing ideal rectified p‐n junctions taking advantage of this unique structure. Finally, the foregrounds of new quantum states driven by this chemical reaction are prospected.
