Magnetic Properties and Crystallization of Co-pt Amorphous Metallic Alloys

Effect of minor Co additions on the crystallization and magnetic properties of Fe(Co)NbBCu alloys

The effect of partial replacement of Fe by Co (up to 8 %) on thermal stability, structure and magnetic properties of FeNbBCu alloys has been explored in this paper. The results indicate that Co reduces the stability against crystallization of the amorphous alloy and stabilizes the nanocrystalline phase prior to the further precipitation of metastable boride phases.

Computer simulation of magnetic properties of Re-Tb amorphous alloys

Using the Monte Carlo method in the frame of the Heisenberg model we performed simulation of magnetic properties of Re100-xTbx (x=5–91 at. %) amorphous alloys and of pure amorphous Tb. Exchange interaction between the nearest neighbours and random uniaxial anisotropy were taken into account in the Hamiltonian. We calculated temperature dependence of magnetization, Edwards–Anderson order paramet...

Some magnetic properties of platinum-rich Pt-Fe alloys

2014 Measurements of magnetic susceptibility and spontaneous magnetization on face centred cubic platinum-iron alloys having compositions around Pt3Fe and also on alloys with lower iron contents, are reported. In the Pt3Fe superlattice region the alloys appear to be antiferromagnetic when ordered and ferromagnetic when disordered. The more dilute alloys are ferromagnetic, even down to 2 at. % o...
