Phys. Rev. Lett. 99, 147208 (2007) [4 pages]Controlling the Magnetic Ground State in Cr1-xVx FilmsReceived 23 June 2007; published 5 October 2007 We demonstrate the ability to control the magnetic phase diagram of Cr1-xVx(110) thin films grown on a W(110) substrate. Using angle-resolved photoemission, we have mapped paramagnetic and commensurate and incommensurate antiferromagnetic phases as a function of temperature, film thickness, and composition. We show that surface-localized electron states play a key role in the observed phase behaviors and suggest from this that it might be possible to control the magnetic phase by applying an external electric field. © 2007 The American Physical Society URL:
