- Title
Tunneling magnetoresistance and Hall effect of granular ferromagnetic metals.
- Authors
Meılikhov, E. Z.
- Abstract
It is shown that two circumstances must be taken into account in order to describe the tunneling magnetoresistance and Hall effect in granular ferromagnetic metals: 1) the size variance of the metallic granules and 2) the percolation character of the tunneling conductivity of the system, determining the optimal (temperature-dependent) size of the granules through which current transport occurs. This complicates the dependences of the magnetoresistance and Hall resistance of the system on its magnetization and temperature. © 1999 American Institute of Physics.
