The evolution and magnetic behaviour of NiO-Ni(OH)2 core-shell nanostructures with different thicknesses of the hydroxide shell have been studied. The nickel hydroxide shell is found to alter the magnetic characteristics of nickel oxide at low temperatures and explains the origin of the exchange bias effect due to the antiferromagnetic NiO core and a ferromagnetic nickel hydroxide shell.
研究了不同厚度氢氧化物壳层的 NiO-Ni(OH)2 核壳纳米结构的演变和磁行为。发现镍氢氧化物壳层在低温下改变了氧化镍的磁特性，并解释了由于反铁磁 NiO 核和铁磁镍氢氧化物壳层而产生的交换偏置效应的起源。
