“…Perovskite oxides (ABO 3 ) have attracted much attention in the last few decades for their wide applications in electronics, energy storage devices, and others. , On altering the cationic composition at the A or B site of the oxide sample, − several interesting properties result. The properties also depend on the preparation methods and the nature of the sample (in quality, purity, and crystallinity).…”

High-purity single crystals of Sm 1−x YxFeO 3 (x = 0.7, 0.5, and 0.3) were grown in an optical floating zone furnace. Using the zone refining process concomitantly with floating zone growth, we eliminated the impurity phases detected in the synthesized polycrystalline orthoferrite compounds. The zone refining method is very effective in obtaining samples with high purity, especially when trace impurities have a notable influence on physical properties, such as in the case of Sm 0.5 Y 0.5 FeO 3 . The magnetic characteristics of the grown Sm 1−x Y x FeO 3 crystals with varying Y contents are entirely free of spurious effects from impurities that are present in their ceramic or polycrystalline versions. Consequently, we could detect interesting spin configurations and spin reorientation transitions in these high-purity crystals. Sm 0.5 Y 0.5 FeO 3 shows temperature-dependent exchange bias behavior along the a-orientation, which diminishes beyond the spin reorientation temperature. Consecutive MH loops measurements result in athermal-type exchange bias behavior.

The magnetic properties of disordered Nd0.5Ba0.5Mn0.5Fe0.5O3−δ/2 and ordered NdBaMnFeO6−δ perovskites were investigated through temperature- and field-dependent DC-magnetization measurements. The temperature dependence of magnetic susceptibilities revealed that antiferromagnetic ordering occurs at temperatures below 185 K for the disordered Nd0.5Ba0.5Mn0.5Fe0.5O3‑δ/2 sample, whereas the ordered NdBaMnFeO6−δ perovskite exhibited a paramagnetic state throughout the entire temperature range examined. Notably, the disordered sample exhibited a glassy state, even at room temperature, which transformed into an antiferromagnetic state under higher applied magnetic fields. The magnetic ordering in the disordered Nd0.5Ba0.5Mn0.5Fe0.5O3‑δ/2 perovskite and the magnetic-disordering state in the structurally ordered NdBaMnFeO6‑δ perovskite could be attributed to the alteration of the oxidation state of Mn.
