An efficient fast hydrothermal method was used to synthesize Co_1-xPd_xFe₂O₄ (x = 0, 0.05, 0.1 and 0.5) nanocrystalline powders, where Co²⁺ was substituted with Pd²⁺ ions. The materials crystallize within the spinel structure (Fd-3m) with crystallites sizes varying between 5.6 and 17.6 nm. The particles present a cubic shape for x = 0 and x = 0.1 samples and the presence of Pd in samples was confirmed by Energy-dispersive X-Ray spectroscopy (EDX) analysis. The magnetic hysteresis loops indicate that the saturation magnetization decreases with the increase once with of the Pd²⁺ amount substitution (from ~52 emu/g for x = 0–~7 emu/g for x = 0.5).

使用高效的快速水热法合成Co _1-x Pd _x Fe ₂ O ₄（x = 0、0.05、0.1和0.5）纳米晶体粉末，其中Co ²⁺被Pd ²⁺离子取代。材料在尖晶石结构（Fd-3m）中结晶，微晶尺寸在5.6和17.6 nm之间变化。对于x = 0和x = 0.1样品，颗粒呈立方体形状，并且样品中Pd的存在通过能量色散X射线光谱（EDX）分析得以确认。磁滞回线表明饱和磁化强度随着Pd ²⁺量的替换一次增加而降低（对于x = 0，从〜52 emu / g = 0 =〜7 emu / g）。
