Peculiar magnetic and electrical properties near structural percolation in metal-insulator granular layers
Abstract
We study CoFe/Al2O3 multilayers, varying from granular to continuous structure with CoFe nominal thickness (10 Angstromless than or equal totless than or equal to18 Angstrom). Structural percolation takes place at t=t(c)approximate to18 Angstrom, changing from activated to metallic conductance. A sharp anomaly in ac coercivity of magneto-optical Kerr effect and in magnetization M by superconducting quantum interferometer device is found at t=t*approximate to17 Angstrom, interpreted as transition from superferromagnetism (by dipolar coupled CoFe clusters) to exchange ferromagnetism. Onset at t=t* of anisotropic magnetoresistance (AMR) is attributed to skew scattering of bandlike electrons within giant fractal clusters. These structures may cause the observed Barkhausen noises in M and AMR at tapproximate tot*, disappearing at t>t*. (C) 2004 American Institute of Physics.
