Abstract Terahertz (THz) radiation produces complex and intriguing interactions with many of the magnetically ordered materials. We introduced a THz time-domain spectroscopy with a temperature control attachment to investigate thermally tunable terahertz magnetic responses of TbFeO3. Ferromagnetic (FM) resonances and antiferromagnetic (AFM) resonances were excited simultaneously at T = 3–290 K. The performance of temperature effect on resonances was assessed by their transmittance, resonant frequency shifts and a defined quality factor (Q-factor, Q = ν0/Δν). Transmittance, defined Q-factor and frequency shifts were introduced to assess the thermally tunable performances of terahertz magnetic responses. Overall increased transmittance, increased Q-factor and blue shifts were observed as temperature cools. This will be beneficial to the THz spectroscopic application in controlling responses of various materials.

TbFeO 3 陶瓷的热可调太赫兹磁响应

摘要 太赫兹 (THz) 辐射会与许多磁性有序材料产生复杂而有趣的相互作用。我们引入了带有温度控制附件的太赫兹时域光谱来研究 TbFeO3 的热可调太赫兹磁响应。铁磁 (FM) 共振和反铁磁 (AFM) 共振在 T = 3–290 K 时同时激发。温度对共振的影响通过它们的透射率、共振频移和定义的品质因数（Q 因子，Q = ν0/Δν)。引入透射率、定义的 Q 因子和频移来评估太赫兹磁响应的热可调性能。随着温度的降低，观察到整体透射率增加、Q 因子增加和蓝移。
