Magnetic racetrack memory is a pioneering 3D storage technology that was invented by IBM in 2008. The memory has the potential to be faster than the hard disk drive, whilst also offering orders of magnitude higher storage density. Today, the use of planar nanowires in prototype magnetic racetrack memory is limiting its performance due to power consumption whilst writing data. Recent theoretical work has indicated that the use of cylindrical nanowires will allow much lower power consumption. Such wires are difficult to fabricate using conventional lithography but can be achieved using 3D processing techniques.Dr Sam Ladak has recently pioneered a novel fabrication method to realise 3D magnetic nanowires and by working directly with IBM, Zurich we have demonstrated that these nanowires can be measured using standard magnetic techniques. This project will utilise a new 3D lithography system and our recently developed technique to manufacture magnetic nanowires in the racetrack geometry. We will aim to manufacture and characterise cylindrical magnetic nanowires systems that have the potential to produce a step-change in prototype memory technologies.

磁性赛道内存是IBM在2008年发明的一项开创性的3D存储技术。内存的潜力比硬盘驱动器更快，同时还提供了更高的存储密度的订单。如今，在原型磁性赛道内存中使用平面纳米线在撰写数据时限制了其性能。最近的理论工作表明，使用圆柱纳米线将允许较低的功耗。这样的电线很难使用常规光刻来制造，但是可以使用3D处理技术来实现。DrSam Ladak最近开创了一种新型的制造方法，可以意识到3D磁性纳米线，并直接与IBM合作，我们证明了这些纳米线可以使用标准磁性磁性技术进行测量。该项目将利用一种新的3D光刻系统，我们最近开发的技术在赛道几何形状中生产磁性纳米线。我们将旨在制造和表征圆柱磁性纳米线系统，这些系统有可能在原型内存技术中产生逐步变化。
