Overview

abstract

• The magnetic anisotropy energy (MAE) of 3d transition-metal wires is calculated self-consistently as a function of length, width, structure, and d-band filling. One-dimensional infinite chains show MAEșs which are an order of magnitude larger than in two-dimensional thin films. A further enhancement is often obtained by reducing the chain length 1(1 ≤ 20 atoms). The MAE of multichains (ladders) oscillates as a function of chain width and depends strongly on the transversal structure. The easy axis of Co wires changes from in-line to off-plane after deposition on Pd(110). Ladders and deposited chains show important in-plane anisotropies. © 1998 American Physical Society.
