Magnetic particles for medical applications by glass crystallisation

For the first time we used the glass crystallisation method for preparation of nanocrystalline magnetite/maghemite powders the only magnetic materials accepted for medical applications. A dodecane-based ferrofluid from maghemite was prepared and characterised. Specific surface and XRD were determined on powders. Hysteresis loops and M-T curves were obtained by VSM. AC susceptometry was done on the ferrofluid.
