Abstract

The results of studies carried out on the effect of magnetic field on the ageing of island silver films, deposited on glass substrates held at room temperature in a vacuum of 2 × 10-6 Torr are presented in this article. The effect of magnetic field on the occurrence of large scale coalescence (LSC) is studied through the repeated deposition technique. A magnetic field of the order of 100 Oe reduces the ageing rate due to the flattening of islands but variation of the field in the same range does not affect ageing significantly. The effect of magnetic field is more pronounced on smaller islands than on larger ones. The application of magnetic field causes LSC to occur at an earlier stage.
