Abstract
DC and AC susceptibility measurements on Fe-SiO2 alloys have been carried o ut from room temperature to liquid He temperature in the zero field-cooling (ZFC) and the field-cooling (FC) mode. The magnetization in the ZFC mode i ncreases rapidly below a characteristic temperature, T-c, and decreases bel ow the freezing temperature, T-f, both of which depend on the applied magne tic field, frequency and Fe concentration. A magnetic phase diagram is desc ribed from these observations. (C) 1999 Elsevier Science B.V. All rights re served.
