The temperature and time dependence, in different magnetic fields, of the field-cooled and zero-field-cooled magnetisation on ball-milled nanocrystalline Fe has been studied. The results indicate the existence, below about 70 K, of a disordered frozen magnetic state which is erased by applying an external field H = 1000 Oe, favouring the ferromagnetic order.

Abstract
The temperature and time dependence, in different magnetic fields, of the field-cooled and zero-field-cooled magnetisation on ball-milled nanocrystalline Fe has been studied. The results indicate the existence, below about 70 K, of a disordered frozen magnetic state which is erased by applying an external field H = 1000 Oe, favouring the ferromagnetic order.File in questo prodotto:
