Preparation of Nanocrystalline BaFe12 − 2x Co x Ti x O19 by Ball
Milling Method and their Magnetic Properties
Nanocrystalline BaFe12−2x Cox Tix O19 with 0 ≤ x ≤ 1 were
prepared by a simple method of ball milling. Magnetic and SEM
measurements show that the coercive field and average grain size
is decreasing with the increase of Co-Ti substitution.

Multistream Instability in Two and Three-Species Plasmas
A detailed parametric investigation of the linear dispersion
relation of electron-ion (e-i) and electron-electron-ion (e-e-i)
in the hydrogen plasma fluid is carried out in order to
determine the different current driven instabilities that can
exist in each case.
