    Magnetic properties of amorphous Fe3O4-CaO-SiO2 are described in terms of the microscopic structure. The amorphous region and magnetization strengths for the system were determined, while measurements of the temperature dependence of magnetization revealed no clear Curie temperature; this was attributed to thermal decomposition of the ferrimagnetic crystalline phas...

    While much is known about the large magnetic moment of Fe8 N thin films, little work has been done on bulk FeN material. Bulk FeN was prepared by pressure-forming ¿-Fe2O3 powder, reduction in H2 and sintering at 700 to 800°C in NH3-H2, followed by gradual cooling or by quenching from different temperatures. It was found that under... View full abstract»

    A new framework uniting classical and quantum physics, along with implications for the study of magnetic materials, are discussed. Features of this framework include emphasis on the Schrödinger representation of time-dependent wave functions, which alone enables a continuous transition from classical to quantum mechanical phenomena, and the adoption of an "electron field" model, replacing the vor...

    The uniaxial magnetic anisotropy (Ku) of evaporated Permalloy films of different thicknesses was measured. For thinner films, measurements relied on the magnetoresistive (¿R) effect. Although there was considerable scattering in the results, Ku tended to decrease as films were made thinner than 500 Å, and disappeared at around 100 to 300 Å. This decrease is thought to be r...
