Experimental Investigation of the Properties Absent in Bulk Samples

2 Experimental Investigation of the Properties Absent in Bulk Samples 

1 Room-Temperature Ferromagnetism in Nanomaterials of Non-magnetic (in Bulk Samples) Oxides 

Searching for high-temperature ferromagnetic compounds based on semiconducting or insulating oxides is actually one of the main research topics of many physical and chemical laboratories. This is because room-temperature ferromagnetism is 

In Fig. 4.1, we show the room-temperature magnetization-field curves of several Ce02 samples. It is obvious from the M H) curves that the as-prepared and 500 °C heated nanoparticles show ferromagnetic behaviour with coercivity 100 Oe. On the other hand, the ferromagnetism is suppressed in the 1,000 °C heated sample
