DESCRIPTION:Spintronics is a field of research that harnesses the electron
 ’s spin to create novel materials with exotic properties and devices esp
 ecially those for storing digital data that is the lifeblood of many of th
 e most valuable companies today. Spintronics has already had two major tec
 hnological successes with the invention and application of spin-valve magn
 etic field sensors that allowed for more than a thousand-fold increase in 
 the storage capacity of magnetic disk drives that store ~70% of all digita
 l data today. Just recently\, after almost a 25-year exploration and devel
 opment period\, a high performance nonvolatile Magnetic Random Access Memo
 ry\, that uses magnetic tunnel junction memory elements\, became commercia
 lly available. A novel spintronics memory-storage technology\, Magnetic Ra
 cetrack Memory is on track to become the third major success of spintronic
 s. Racetrack Memory is a non-volatile memory in which data is encoded in m
 obile chiral domain walls that are moved at high speeds by spin currents t
 o and thro along synthetic antiferromagnetic racetracks1-3. \n\nIn this le
 cture I will discuss the developments of spintronics over the past 35 year
 s and its future potential and prospects for both conventional memory-stor
 age as well as for cryogenic racetrack memory technologies to support cryo
 genic quantum computing systems.\n\n1: Parkin\, S. S. P.\, Hayashi\, M. &
