Magnetic Polarons in Dilute Ferromagnetic Oxide Films and Nanoparticles

Transport and magnetic properties in ferromagnetic manganese-oxide thin films

The transport and magnetic properties in ferromagnetic manganese-oxide thin films are studied based on the model of the coupling between the mobile d-electrons and the core spins in Mn ions. The spontaneous magnetization and the resistivity are obtained for various magnetic fields and temperature. The resistivity in absence of magnetic field and the magnetoresistance exhibit maxima near the Cur...

Magnetic Circular Dichroism of a Dilute Ferromagnetic Alloy (ni-mn)

There is much interest and debate concerning the origin of ferromagnetism in dilute alloys of MnxGa1-xAs and other magnetically doped semiconductors [1]. The Mn acts as an acceptor introducing itinerant holes into the semiconductor. The ferromagnetic (FM) coupling between the magnetic Mn is thought to be via RKKY screening by the itinerant hole gas [2]. This coupling induces FM order at concent...
