Summary: | The structural and magnetic properties of Fe 10
at% doped SnO
2 powders milled for different times have been investigated. XAS results demonstrate the dilution of Fe atoms in the rutile structure after 5
h of milling. Fe atoms have almost one oxygen vacancy near neighbour. At RT the sample presents the superposition of paramagnetic and ferromagnetic behaviours. When temperature decreases a progressive blocking process was observed. Below 100
K a field shift of hysteresis loops is evident indicating magnetic coupling between ferromagnetic/antiferromagnetic phases. |
