Finite-size effects in nickel nanowire arrays

Finite-size effects in nickel nanowire arrays Nickel nanowire arrays with diameters in the range 30–500 nm have been fabricated by electrochemical deposition into nanoporous, single-crystal mica templates, which allow measurements of the magnetic properties of nickel nanowire arrays at high temperatures. The Curie temperature is found to be reduced by as much as 51 K for the 30 nm diameter nanowires. The Curie temperature shift with wire diameter follows the finite-size scaling relation with λ = 0.94 and ξ 0 = 22 Å . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)

Abstract

Nickel nanowire arrays with diameters in the range 30–500 nm have been fabricated by electrochemical deposition into nanoporous, single-crystal mica templates, which allow measurements of the magnetic properties of nickel nanowire arrays at high temperatures. The Curie temperature is found to be reduced by as much as 51 K for the 30 nm diameter nanowires. The Curie temperature shift with wire diameter follows the finite-size scaling relation with λ = 0.94 and ξ 0 = 22 Å .
