Magnet properties of Mn70Ga30 prepared by cold rolling and magnetic field annealing

Isotropic, high coercive field in melt-spun tetragonal Heusler Mn3Ge

“…To give a comparison with the related Mn-Ga system, the optimized magnetic properties obtained in D0 22 Mn 70 Ga 30 yielded a coercive field of 1.24 T and a remanence of 190 kAm −1 after cold-rolling and field annealing. 31 These values roughly correspond to half the coercivity but double of the remanence as compared to Mn 3 Ge in this study.…”

Magnetic properties of(Fe1−xCox)2Balloys and the effect of doping byEdström1, Werwiński2, Iuşan3 et al. 2015Phys. Rev. B

“…Recently, however, the availability (and thus price) of the rare-earth elements became rather volatile, calling for development of replacement materials which would use less or none of * Corresponding author: jan.rusz@physics.uu.se the rare-earth elements. Intense research efforts have started worldwide, revisiting previously known materials, such as Fe 2 P [5][6][7], FeNi [8], or Fe 16 N 2 [9], doing computational data mining among the large family of Heusler alloys [10], exploring the effects of strain [11][12][13][14][15][16][17] and doping by interstitial elements [18,19], multilayers such as Fe/W-Re [20] or, as a limiting case of multilayers, the L1 0 family of compounds [21], or promising Mn-based systems [22][23][24][25][26][27], among others.…”

Consolidation of cobalt nanorods: A new route for rare-earth free nanostructured permanent magnets

“…Among the different candidates, Mn-and Fe-based alloys [7,8,9] are meeting the abundance criterion, while Co-based alloys [10,11,12] benefit from the high intrinsic anisotropy of cobalt.…”
