Permanent Magnet Properties in Fe-Pt-Nb System Alloys

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...

- Based Rare - Earth - Free Permanent - Magnet Alloys

This study presents the structural and magnetic properties of melt-spun , , and alloys. Appreciable permanent-magnet properties with a magnetocrystalline anisotropy of about 9.6–16.5 , a magnetic polarization –10.6 kG, and coercivities –3.0 kOe were obtained by varying the composition of these alloys. Structural analysis reveals that the positions of x-ray diffraction peaks of show good agreeme...

MAGNETIC STATES INSTABILITY OF Pt-Fe ALLOYS

Neutron-diffraction measurements have been used to 'determine the temperature and composition dependences of the ordered single crystals of Pt-Fe alloys containing 32, 30.5 and 28 at% of iron. A qualitative model for the complex antiferromagnetic ordering in the system based on the experimental data and band structure calculations has been proposed. The ordered Pt-Fe alloys with more than 36 at...
