The effect of evolving grain shape and alignment on the coercivity in thermomechanically deformed Nd13.9(Fe0.92Co0.08)80.3B5.3Ga0.5 permanent magnets

TL;DR: In this article, the effect of the alignment on the coercivity has been studied using measurements of the temperature dependence of coercivity, which was performed using a well-known phenomenological model, and it was discovered that the trends in α and N eff as a function of crystallographic grain alignment are the opposite to what is expected and measured previously in analogous sintered samples of varying crystallographic alignment.
Journal ArticleDOI

Lattice-driven magnetic transitions in Al(Fe,T)2X2 compounds

TL;DR: In this paper, detailed composition, lattice parameters and magnetic transition temperatures in the ferromagnetic intermetallic compound AlT2X2 with the Mn2AlB2-type crystal structure were analyzed and it was observed that compositional variation alters specific bonds responsible for the magnetic phase transition response.
Journal ArticleDOI

Toward tailored functionality of titania nanotube arrays: Interpretation of the magnetic-structural correlations

TL;DR: In this paper, ordered arrays of titania nanotubes are synthesized electrochemically and are subjected to isochronal annealing treatments in various atmospheres (oxygen-rich, oxygen-deficient and reducing) to modify their morphology, crystal and electronic structure.
Journal ArticleDOI

Phase-separated alloys for bulk exchange-biased permanent magnets

TL;DR: In this article, a two-phase materials system composed of ferromagnetic FeCo and antiferromagnetic, nominally equiatomic AuMn was carried out for metallurgical synthesis from the melt of bulk permanent magnets.
Journal ArticleDOI

Effect of Ambient Aging on Heat-Treated Mechanically Alloyed Mn-Al-C Powders

TL;DR: The effect of ambient aging upon the magnetic and structural properties of heat-treated mechanically alloyed Mn0.53Al0.47-xCx powders was systematically investigated as mentioned in this paper.
