Low-Temperature Polyol Synthesis of Nanocrystalline Co and CoPt Alloys

Chávarri-Pajares E., Pérez J., Perales-Perez O., Singhal R., Tomar M.S., University of Puerto Rico, PR

The strong size-dependent magnetic properties of transition metal nanocrystals can be used to estimate the scaling limits of magnetic storage, a key component of information technology. High Ku (magnetocrystalline anisotropy constant) materials become then very [...]

A Novel Synthesis of Co@Au Nanoparticles and Characterization

Ban Z., O'Connor C.J., University of New Orleans, US

A homogeneous non-aqueous solution reactions method has been developed to prepare gold-coated cobalt (Co@Au) nanoparticles. After the sample was washed with 8% HCl, TGA, XRD, TEM, and magnetic measurements SQUID are utilized to characterize the [...]
