| description | The paper presents the results of an experimental study of the magnetic properties of a magnetic fluid, the storage of a well-developed system of aggregates that have a real magnetic moment. An analysis of the magnetic state of the investigated medium was carried out by studying the processes of magnetization of a magnetic fluid in a magnetostatic and variable magnetic fields. It was determined that when the initial sample was diluted with a dispersion medium, the magnetic moments of the dispersed particles were ordered in a limited volume. This process resulted in the formation of large elastic aggregates, which possess their own magnetic moment. It was established that the processes of magnetization relaxation in such a medium are analogous to the relaxation of magnetically ordered systems with short-range order - elastic dipole glasses. When the sample temperature is lowered below the curing temperature, the system is transformed into a dipole glass, similar to the Ising one. |
