Abstract
Effects of temperature changes on aging phenomena are studied for the spin- glass-like phase of a ferromagnetic fine particle system. The results obtai ned during the short experimental periods are, in appearance, asymmetric ab out temperature changes. However, the extension of the periods shows that t he effects of temperature changes are symmetric. These results can be expla ined by the droplet model well. [S0031-9007(99)09194-2].
