“…The fully substituted sample Sc 0.28 Ti 0.72 Mn 2 does not exhibit a linear 1/χ Curie-Weiss behavior and is closer to a nearly temperature-independent paramagnet with χ 0 = 10 −3 emu•mol −1 . This is in line with the "non-magnetic" Pauli paramagnetism reported for its TiMn 2 and ScMn 2 parents [41,42].…”

(Sc,Ti)Fe2 Laves phases present a relatively unique case of first-order ferro-ferromagnetic transition originating from an instability of the Fe moment. In addition to large magnetoelastic effects making them potential negative thermal expansion materials, here, we show that Sc0.28Ti0.72Fe2 and related alloys also present sizable magnetocaloric and magnetoresistance effects. Both effects are found substantially larger at the ferro-ferromagnetic transition (Tt1) than near the Curie temperature TC, yet they remain limited in comparison to other classes of giant magnetocaloric materials. We suggest a strategy to improve these properties by bringing the transition at Tt1 close to TC, and test its possible realization by Co or Mn for Fe substitutions. The structural and magnetic phase diagrams of Sc0.28Ti0.72Fe2−xTx alloys with T = Mn or Co are explored. Substitutions for Fe by adjacent Mn or Co elements give rise to a breakdown of the long-range ferromagnetic order, as well as a swift disappearance of finite moment magnetism.

“…The Fe 2.25 V 0.75 Al single crystal. using the above described Czochralski method, several systems of the single crystals were obtained as: R 3 Co; R 3 Ni; R 3 Rh; R 3 Ir [3][4][5][6][7][8][9][10][11][12][13][14][15][16]; Fe 3−x V x Al [17,18]; RFe 4 Al 8 [19][20][21][22][23][24][25][26][27]; RMn 2 [28][29][30][31][32][33][34][35]; GdTX [36][37][38][39][40][41]; Gd 7 T 3 [42] (R: rare earth; T: transition metal 3d, 4d, 5d; X metal p). Some measurements may be realized only using the single crystals for example the XPS electronic structure of the RMn 2 intermetallics.…”
