We demonstrate lifetimes of Zeeman populations and coherences in excess of 60 sec in alkali-metal vapor cells with inner walls coated with an alkene material. This represents 2 orders of magnitude improvement over the best paraffin coatings. We explore the temperature dependence of cells coated with this material and investigate spin-exchange relaxation-free magnetometry in a room-temperature environment, a regime previously inaccessible with conventional coating materials.
我们展示了在碱金属蒸汽室内壁涂有烯烃材料的情况下，塞曼群体和相干性的寿命超过 60 秒。这比最好的石蜡涂层提高了两个数量级。我们探索了这种材料涂层的温度依赖性，并研究了在室温环境下无自旋交换弛豫的磁强计，这是以前用常规涂层材料无法实现的。
