The aim of the project is to synthesize a systematic series of novel colossal magnetoresistance manganese, cobalt and iron based transition metal perovskite oxides in the forms of nano-structures, nano-structured composites and single crystals using advanced nano-technology and crystal growth techniques. Extensive fundamental studies on magnetoresistance, spin and change ordering, and nano-scale behaviors will be carried out by neutron diffraction, synchrotron radiation, transport and magnetic measurements over a wide temperature range and magnetic fields. The outcomes of this project are likely to lead to a better undertanding of the colossal magnetoresistance mechanisms, the discovery of fascinating new physical phenomena and suitable magnetoresistance materials for superior magnetic recording, sensing and switch devices
