N2 - Intense terahertz (THz) radiation in free space offers multifaceted capabilities for accelerating electrons, understanding mesoscale architecture in (bio)materials, elementary excitation, etc. However, the lack of high-beam-quality, high-stability, low-cost, and easy-to-implement high-field THz sources impedes the proliferation of strong-field THz applications. Recently popularized spintronic THz emitters (STEs), with their versatility, such as ultrabroadband, cost-effectiveness, large-size, and ease-for-integration, have become one of the most promising alternatives for the next generation of intense THz sources [1,2]. Nevertheless, the typical W|Co20Fe60B20|Pt necessitates an external magnetic field to saturate magnetization for stable operation, limiting its scalability for achieving a higher THz field with uniform distribution over larger sample areas.
