Abstract
One-dimensional, single-crystalline BiFeO(3) nanowires presenting a diameter of 45-200 nm and a length from hundreds of nanometres to several microns have been prepared using an improved hydrothermal method. The characterization results of ZFC and FC magnetizations at different temperatures indicate that single-crystalline BiFeO(3) nanowires show a spin-glass transition below the freezing temperature of 55 K.
摘要
采用改进的水热法制备了直径为 45-200nm、长度从几百纳米到几微米的一维、单晶 BiFeO(3)纳米线。不同温度下 ZFC 和 FC 磁化的表征结果表明，单晶 BiFeO(3)纳米线在 55K 的冻结温度以下表现出自旋玻璃转变。
