Effect of residual strain, grain size and Fe impurities on magnetic properties of nanocrystalline Ni(Fe) alloys

Magnetic properties of ball-milled and relaxation heat-treated Ni have been investigated. Two stages of energy relaxation during isochronal annealing have been distinguished. It has been shown that the changes in the magnetic parameters can rather be interpreted by the presence of Fe clusters produc...

Summary:Magnetic properties of ball-milled and relaxation heat-treated Ni have been investigated. Two stages of energy relaxation during isochronal annealing have been distinguished. It has been shown that the changes in the magnetic parameters can rather be interpreted by the presence of Fe clusters produced by the contamination and their dissolution, than by the random anisotropy model.
