Spin diode is important prerequisite to practical manifestation of spin electronics. Yet, a functioning magnetic diode at room temperature is still illusive. Here, we reveal diode-type phenomena due to magnetic charge mediated conduction in artificial honeycomb geometry, made of concave shape single domain permalloy element. We find that honeycomb lattice defies symmetry by populating vertices with low and high multiplicity magnetic charges, causing asymmetric magnetization, in applied current of opposite polarity. High multiplicity units create highly resistive network, thereby inhibiting magnetic charge dynamics propelled electrical conduction. However, practical realization of this effect requires modest demagnetization factor in constituting element. Concave structure fulfills the condition. Subsequently, magnetic diode behavior emerges across broad thermal range of T = 40 K–300 K. The finding is a departure from the prevailing notion of spin-charge interaction as the sole guiding principle behind spintronics. Consequently, a new vista, mediated by magnetic charge interaction, is envisaged for spintronic research.

自旋二极管是实现自旋电子学实用化的重要前提。然而，在室温下工作的磁性二极管仍然是虚幻的。在这里，我们揭示了由于由凹形单畴坡莫合金元素制成的人造蜂窝几何结构中磁电荷介导的传导引起的二极管型现象。我们发现蜂窝晶格通过在具有相反极性的施加电流中填充具有低和高多重磁荷的顶点来违反对称性，导致不对称磁化。高多重单元创建高电阻网络，从而抑制磁电荷动力学推动的电传导。然而，这种效果的实际实现需要构成元素的适度退磁因子。凹面结构满足条件。随后，T  = 40 K–300 K。这一发现背离了自旋电荷相互作用作为自旋电子学背后唯一指导原则的流行概念。因此，为自旋电子研究设想了一种由磁电荷相互作用介导的新前景。
