n型轻掺杂硅衬底上电沉积铁纳米结构的低场微波吸收和磁电阻效应
Low-field microwave absorption and magnetoresistance in iron nanostructures grown by electrodeposition on n-type lightly-doped silicon substrates
摘要：
在本研究中，我们研究了电沉积在轻掺杂（100）n型硅衬底上的铁纳米团簇的磁性、表面形貌和晶体结构。我们的目标是研究Fe/Si横向结构中的自旋注入和探测。在电渗流下获得的样品的特征在于通过磁阻和磁共振测量与循环扫描施加的场，以了解在所产生的样品中的自旋动力学。在磁共振谱中观察到的磁滞现象，加上在非饱和状态下确认低场微波吸收（LFMA）的宽峰的存在，与在磁阻曲线中发现的峰和斜率相关。结果表明，在低阻硅的长距离自旋注入和检测和磁共振技术在这里介绍了作为一个有前途的工具，用于分析电非接触磁阻样品。
英文摘要：
In this study we investigate magnetic properties, surface morphology and crystal structure in iron nanoclusters electrodeposited on lightly-doped (100) n-type silicon substrates. Our goal is to investigate the spin injection and detection in the Fe/Si lateral structures. The samples obtained under electric percolation were characterized by magnetoresistive and magnetic resonance measurements with cycling the sweeping applied field in order to understand the spin dynamics in the as-produced samples. The observed hysteresis in the magnetic resonance spectra, plus the presence of a broad peak in the non-saturated regime confirming the low field microwave absorption (LFMA), were correlated to the peaks and slopes found in the magnetoresistance curves. The results suggest long range spin injection and detection in low resistive silicon and the magnetic resonance technique is herein introduced as a promising tool for analysis of electric contactless magnetoresistive samples.
