TI - Magnetic Phase Control in Monolayer Films by Substrate Tuning JO - Physical review letters VL - 99 SN - 0031-9007 CY - College Park, Md. PB - APS M1 - PreJuSER-58658 SP - 187203 PY - 2007 N1 - Record converted from VDB: 12.11.2012 AB - We propose tailoring exchange interactions in magnetic monolayer films by tuning the adjacent nonmagnetic substrate. As an example, we demonstrate a ferromagnetic-antiferromagnetic phase transition for one monolayer Fe on a TaxW1-x(001) surface as a function of the Ta concentration. At the critical Ta concentration, the nearest-neighbor exchange interaction is small and the magnetic phase space is dramatically broadened. Complex magnetic order such as spin spirals, multiple-Q, or even disordered local moment states can occur, offering the possibility of storing information in terms of ferromagnetic dots in an otherwise zero-magnetization state matrix.
