标题： Synthetic Altermagnets

摘要： 反铁磁体，一种具有类似于d波超导体电子结构的特殊反铁磁体类别，表现出引人注目的特性，在近期研究中引起了广泛关注。 在本文中，我们提出合成反铁磁体，由两个各向异性铁磁层组成，这些层的排列方式使得总净磁化强度为零。 我们研究了这些合成反铁磁体的特性，重点关注它们的电子能带结构、自旋电流、贝里曲率和反常霍尔电导率。 通过为我们的合成反铁磁体开发一个最小模型，我们研究了各向异性耦合强度和自旋轨道耦合等因素对反铁磁体所表现的物理现象的影响。 我们的研究结果为实验实现反铁磁材料开辟了一条新途径，并突显了其在磁电、磁光和自旋电子器件中的潜在应用。 显示英文摘要

摘要： Altermagnets, a distinct class of antiferromagnets with electronic structures resembling those of d-wave superconductors, exhibit intriguing properties that have gained significant attention in recent research. In this article, we propose synthetic altermagnets, composed of two anisotropic ferromagnetic layers arranged such that the total net magnetization is zero. We investigate the properties of these synthetic altermagnets, focusing on their electronic band structures, spin current, Berry curvature, and anomalous Hall conductivity. By developing a minimal model for our synthetic altermagnets, we examine the influence of factors such as anisotropic coupling strengths and spin-orbit coupling on the physical phenomena altermagnets manifest. Our findings open a new path for the realization of altermagnetic materials experimentally and highlight their potential applications in magneto-electronics, magneto-optics, and spintronics devices.
