The bad news: K's boss got passed up for the Nobel Prize for Physics.
The good news: He got a ton of citations in the Scientific Background on the Nobel Prize in Physics 2007 paper, including the following short but very important paragraph:
The next step was to investigate the dependence of the coupling on the thickness of the intermediate non-magnetic layers. Several groups identified a change of sign with increasing thickness (13,15,16,17,18). A thorough study of the dependence of the oscillatory behaviour on the thickness of the non-magnetic layer, its dependence on the material of the non-magnetic layer as well as on the dependence of the material of the magnetic layer itself was made by Parkin (1). Here he actually utilized the GMR effect as a tool to study this dependence. In the preparation of the multilayers Parkin used a magnetron sputter deposition technique. With this method it was possible to prepare a large number of samples under comparable conditions. This extensive work was important for the further development of the GMR effect into a working device (20,21,22).Most of the popular press articles (including the one above from Nature) talk about this in terms of Stuart applying industrial processes towards product development, but miss that this work advanced the basic understanding of how GMR worked and demonstrated that it was a general phenomenon.
The cool news: K was an author on citation #18 and his name is in the Scientific Background paper.
