Abstract
Nanoscale CoPt grains were prepared within protein shells from aqueous reac tants, A series of particles with varying Co:Pt ratios was used to explore the transition from superparamagnetic to ferromagnetic behavior at room tem perature. TEM and electron diffraction confirmed ordered fct CoPt phases wi th an average grain size of 4.1 nm, Magnetic characterization was performed at room temperature using VSM. The use of this system to prepare high-dens ity recording media is discussed.
