Show Abstract
We created helical magnetic structures by depositing in sequence layers of lanthanum and iron (each 30 Å thick) on a substrate rotating in a fixed field of a few Oe. The magnetic field was sufficient to define the magnetization of each layer during growth without disturbing the magnetization of the layers already formed. As a result, the imprinted helical magnetic structure had a chirality given by the direction of rotation of the substrate; the pitch was given by the speed of rotation and the rate of deposition. This finding indicates that it is possible to engineer mesoscopic magnetic structures. © 1998 American Institute of Physics.

Show Abstract
An analytical method is developed for the effective magnetostriction of magnetostrictive composites based on Green’s function technique. For an elastically isotropic composite of magnetostrictive and nonmagnetostrictive phases, the analytical results give explicit effective-medium approximate formulas for the effective magnetostriction that fit well with available experimental data for SmFe2-based composites. © 1998 American Institute of Physics.
