“…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.…”

“…12 On the other hand, thus far reported (BH) max value of the MnBi single-phase bulk magnets is less than the half of the theoretical limit. 7,8,[13][14][15][16][17] One of the main challenges to fabricate high performance MnBi bulk magnets is the preparation of a single-phase LTP MnBi alloy. Past studies of MnBi materials have proven that it is extremely difficult to prepare a pure LT MnBi phase in large scale by conventional methods.…”

[5][6][7][8][9][10][13][14][15][16][17][18][19][20][21][22][23][24] The single LTP MnBi formation is impeded by the Mn segregation from the Mn-Bi liquid at the peritectic temperature and the extremely slow diffusion of Mn to combine with Bi for forming MnBi at low annealing temperature (T a < 613 K). 9,25 Recently, we have reported our new efforts in preparing a MnBi bulk magnets with a good balance of remanence and coercivity via a novel processing route with (BH) max value of 7.8 MGOe at room temperature.…”

“…Ферромагнитные свойства и получение интерметаллических компаундов MnBi широко изучаются, как возможная замена редкоземельных металлов в производстве постоянных магнитов [1][2][3][4] и магнитных сред для магнито-оптической записи пленок [5][6][7]. Одним из основных магнитных MnBi компаундов является низкотемпературная фаза LT-MnBi, которая имеет высокую анизотропию и относительно высокую намагниченность, большое фарадеевское вращение [5][6][7].…”
