We consider possible high temperature superconductivity (high-T_c) in transition metal compounds with a cubic zinc-blende lattice structure. When the electron filling configuration in the d-shell is close to d⁷, all three t_2g orbitals are near half filling with strong nearest neighbor antiferromagnetic (AFM) superexchange interactions. We argue that upon doping, this electronic environment can be one of “genes” to host unconventional high T_c with a time reversal symmetry broken d₂z²−x²−y² ± id x²−y² pairing symmetry. With gapless nodal points along the diagonal directions, this state is a direct three-dimensional analogue to the two-dimensional B_1gd-wave state in cuprates. We suggest that such a case may be realized in electron doped CoN, such as CoN_1−xO_x and (H, Li)_1−xCoN.

立方锌混合过渡金属化合物中的非常规高温超导性

我们考虑了具有立方晶状闪锌矿晶格结构的过渡金属化合物中可能存在的高温超导性（高T _c）。当d壳中的电子填充构型接近d ^7时，所有三个t _{2 g}轨道都接近一半填充，具有强烈的最近邻反铁磁（AFM）超交换相互作用。我们认为，在掺杂时，该电子环境可以是“基因”，将主机非常规高之一Ť _Ç与时间反演对称性破d ₂ ž ² - X ² - ý ² ±I二维X ² -y ²配对对称。在沿对角线方向具有无间隙的节点的情况下，该状态直接类似于铜酸盐中的二维B _{1 g} d波状态的三维模拟。我们建议这种情况可以在掺杂电子的CoN中实现，例如CoN _{1- x} O _x和（H，Li）_{1- x} CoN。
