反铁磁体通常具有相当高的磁共振,称为反铁磁共振,其频率高达THz范围。它们是少数几种可以与THz电磁波磁耦合的材料之一,因此是THz技术的重要材料。在这项工作中,我们证明了太赫兹共振特性,如共振频率和因子,反铁磁NiO可以控制在一个很宽的范围内,通过取代各种不同的阳离子的阳离子。我们的讨论延伸到不同的替代阳离子,以及如何影响的共振性能的趋势,这表明反铁磁太赫兹材料的设计的指导方针。
Antiferromagnets generally have a quite high magnetic resonance, as known as the antiferromagnetic resonance, whose frequency goes up to the THz range. They are one of the few materials that can magnetically couple to THz electromagnetic waves and are therefore important materials for THz technologies. In this work, we demonstrate that the THz resonance properties, such as resonant frequency and thefactor, of antiferromagnetic NiO can be controlled over a wide range by substituting thecation with various different cations. Our discussion extends to the trends of how different substitute cations, andimpact the resonant properties, which suggests a guideline for designing antiferromagnetic THz materials.
