Interface between layers of Fe and Hf is studied using magneto‐optical Kerr effect (MOKE) and soft X‐ray absorption spectroscopy (SXAS). Measurements as a function of the Fe layer thickness are done in a single sample by making use of a wedge‐shaped geometry for Fe layer sandwiched between two layers of Hf. SXAS measurements at the L‐edge of Fe provide evidence for interfacial alloying between Fe and Hf layers, with the thicknesses of the intermixed layers at Fe‐on‐Hf and Hf‐on‐Fe interfaces being 0.18 ± 0.05 and 0.27 ± 0.05 nm, respectively. Evolution of the MOKE hysteresis loop with Fe layer thickness gives an effective magnetic dead layer of 0.8 ± 0.1 nm at the two Fe/Hf interfaces together. Precise determination of the thickness of the intermixed layer and the magnetic dead layer using two independent techniques allows us to have a better insight into the interfacial magnetism and origin of magnetic dead layer at Fe/Hf interfaces. Present results suggest that the origin of the effective magnetic dead layer is partly due to modified magnetic moments of Fe and Hf in the intermixed regions and partly due to proximity‐induced magnetic moment in the interfacial Hf layers with its magnetic moment aligned antiparallel to the Fe layer.

磁光克尔效应和软X射线吸收光谱法研究Hf / Fe系统中的界面
利用磁光克尔效应（MOKE）和软X射线吸收光谱（SXAS）研究了Fe和Hf层之间的界面。通过使用夹在两层Hf之间的Fe层的楔形几何形状，在单个样品中完成与Fe层厚度相关的测量。Fe的L边缘的SXAS测量提供了Fe和Hf层之间的界面合金化的证据，Fe-on-Hf和Hf-on-Fe界面上的混合层厚度为0.18±0.05和0.27±0.05 nm，分别。具有Fe层厚度的MOKE磁滞回线的演变在两个Fe / Hf界面处共同产生0.8±0.1 nm的有效磁死层。使用两种独立的技术来精确确定混合层和磁性死层的厚度，使我们可以更好地了解Fe / Hf界面的界面磁性和磁性死层的起源。目前的结果表明，有效磁死层的起源部分是由于在混合区域中Fe和Hf的磁矩发生了变化，部分是由于界面Hf层中的感应磁矩使磁矩与Fe反平行排列而产生的。层。
