局域矩分子系统现已被用作门控自旋电子器件中的传导通道，并且这三个终端器件中的一些甚至可以被视为分子自旋晶体管。在这些系统中，栅极电压可用于调整分子水平排列，而施加的磁场会影响自旋状态，改变磁性，并提供对磁各向异性的见解。最近，使用分子自旋交叉复合物作为传导通道，已经产生了既非易失性又在较高温度下具有功能的器件。事实上，一些设备现已被证明可以在室温下工作。本文回顾了几种分子晶体管，包括那些声称使用单分子磁体 (SMM) 的分子晶体管。
Local moment molecular systems have now been used as the conduction channel in gated spintronics devices, and some of these three terminal devices might even be considered molecular spin transistors. In these systems, the gate voltage can be used to tune the molecular level alignment, while applied magnetic fields have an influence on the spin state, altering the magnetic properties, and providing insights to the magnetic anisotropy. More recently, the use of molecular spin crossover complexes, as the conduction channel, has led to devices that are both nonvolatile and have functionality at higher temperatures. Indeed, some devices have now been demonstrated to work at room temperature. Here, several molecular transistors, including those claiming to use single molecule magnets (SMM), are reviewed.
