摘要:

在这项研究中,新的使用的电磁场分布的局部欺骗表面等离子体激元模式检测电子自旋共振被报道。该模式支持在具有互补金属螺旋结构的谐振器上,该互补金属螺旋结构蚀刻在具有50 $Ω$的特性阻抗的微带线的接地平面上。观察和分析了感兴趣的模式的特性随温度降低的变化。用该共振器记录了标准顺磁样品2,2-二苯基-1-苦肼的电子自旋共振谱,其温度低至10 K。讨论了该模式在微波Rashba场驱动电子自旋共振探测中的潜在应用。

英文摘要:

In this study, novel use of the electromagnetic field profile of a localized spoof surface plasmonic mode to detect electron spin resonance is being reported. The mode is supported on a resonator with a complementary metallic spiral structure, etched on the ground plane of a microstrip line having a characteristic impedance of 50 $Ω$. The change in characteristics of the mode of interest with lowering of temperature has been observed and analyzed. Electron spin resonance spectra of a standard paramagnetic sample, 2,2-diphenyl-1-picrylhydrazyl, are recorded using this resonator down to 10 K. Potential application of the mode in the detection of microwave Rashba field-driven electron spin resonance has been discussed.
