标题： Efficient Spintronic THz Emitters Without External Magnetic Field

摘要： 我们研究了基于非磁性底层采用倾斜角沉积法制备的最新自旋电子太赫兹发射器（W 或 Ta）/CoFeB/Pt 的性能。 在存在或不存在外部磁场的情况下，太赫兹发射幅度保持相同，并且随时间显著稳定。 这种稳定性归因于通过倾斜角沉积底层非磁性层所增强的铁磁层单轴磁各向异性。 我们的发现可用于开发实用的无磁场线偏振太赫兹辐射发射器，可能在未来太赫兹技术中启用新应用。 显示英文摘要

摘要： We investigate the performance of state-of-the-art spintronic THz emitters (W or Ta)/CoFeB/Pt with non-magnetic underlayer deposited using oblique angle deposition. The THz emission amplitude in the presence or absence of an external magnetic field remains the same and remarkably stable over time. This stability is attributed to the enhanced uniaxial magnetic anisotropy in the ferromagnetic layer, achieved by oblique angle deposition of the underlying non-magnetic layer. Our findings could be used for the development of practical field-free emitters of linearly polarized THz radiation, potentially enabling novel applications in future THz technologies.
