Magnetic hysteresis properties of Fe-26Cr-16Co hard magnetic alloys

Hard magnetic properties of melt-spun Mn-Al-C alloys

Structural and magnetic characterization of Mnx−yAl100−x−yC2y (x = {50, 55}; y = {0, 1}) melt-spun ribbons is reported. To obtain the metastable ferromagnetic τ-phase, rapidly solidified alloys were annealed either in a vacuum furnace at 823 K or directly in the vibrating sample magnetometer under applied magnetic field. Optimal magnetic properties were demonstrated by Mn54Al44C2 samples proved...

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...

Magnetic hysteresis in granular CuCo alloys

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...

Magnetic domains in magnetostrictive Fe–Ga alloys

Lorentz microscopy was applied to the observation of magnetic domains in iron-gallium (Fe–Ga) alloys. Results did not show any link between the magnetic domains and the magnetostriction enhancement by Ga addition, but did reveal that the drastic decrease in magnetostriction for Fe–31.2 at. % Ga was due to the presence of large scale precipitates. Magnetic domain features did not change in the a...
