Magnetic imaging of layer-by-layer reversal in Co/Pt multilayers with perpendicular anisotropy
Robinson, M.; Au, Y.; Knepper, J. W.; Yang, F. Y.; Sooryakumar, R. ( 2006-06-15 )For very thin Co layers, the exchange coupling between adjacent Co layers in Co∕Pt multilayers is ferromagnetic and the coupling strength varies nonmonotonically as the nonmagnetic Pt layer thickness (t_Pt) ranges from 3 ... -
Magnetic screening properties of superconductor-ferromagnet bilayers
Houzet, Manuel; Meyer, Julia S. ( 2009-07-14 )We study theoretically the magnetic screening properties of thin, diffusive superconductor/ferromagnet bilayers subject to a perpendicular magnetic field. We find that the effective penetration depth characterizing the ... -

Male pheromone stimulates ovarian follicular development and body growth in juvenile female opossums (Monodelphis domestica)
Harder, John D.; Jackson, Leslie M. ( 2003-02-11 )Female opossums are induced into estrus by direct exposure to a non-volatile pheromone in male scentmarks. Juvenile females develop this responsiveness by 150 days of age (days), and earlier (130 days) if exposed to male ... -
