    Modeling Giant Magnetoresistance and Relative Permeability in Granular Films

    A model for the field dependence of giant magnetoresistance (GMR) in ‘granular’ co-sputtered alloy thin films (based on a relatively simple spin-dependent scattering concept appropriate to superparamagnetic an...

    Giant Magnetoresistance in Single Layer and Multilayer Phase Separating Alloy Films

    The phenomenon of giant magnetoresistance (GMR), previously measured only in multilayer films comprising ferromagnetic layers separated by nonmagnetic spacers, has recently been observed in single layer ‘granu...

    Magnetic Properties of Sputtered Ni/Al Multilayers

    Magnetic properties of sputtered Ni/Al multilayers have been investigated by vibrating sample magnetometry and ferromagnetic resonance. In these compositionally modulated films (CMFs) the Al ‘spacer’ layer thi...

    Mass mortality of Diadema antillarum on the Caribbean coast of Panama

    The ecologically important sea urchin Diadema antillarum suffered mass mortalities in 1983, first noted in Panama and then reported from the rest of the Caribbean. We documented the effects of this mortality at t...
