Abstract

The oxidation of Co films on MgO was investigated. A short annealing formed a 1-nm oxide layer; a long one (90 min) led to complete oxidation. In the CoO_x/Py structures, an exchange bias of 2.5 kOe was detected. It was shown that the initial thickness of the Co layer is the main parameter determining the uniformity of the magnetic state. The results are important for obtaining antiferromagnetic cobalt oxide with the desired properties.

钴薄膜氧化过程的铁磁共振光谱和磁强计研究

研究了Co膜在MgO上的氧化作用。短时间退火形成1 nm的氧化层；长时间（90分钟）导致完全氧化。在CoOx/Py结构中，检测到2.5 kOe的交换偏置。结果表明，Co层的初始厚度是决定磁态均匀性的主要参数。研究结果对获得具有理想性能的反铁磁性氧化钴具有重要意义。
