Magnetism and transport properties of Hf1−xTaxFe2 and Mn2−xCrxSb

Magnetic and magnetocaloric properties of quenched Hf1−xTaxFe2 materials

“…1, it can be seen that with increasing Ta content, the value of T 0 decreases markedly from 255 to 225.5 K with x changing from 0.16 to 0.17, and the magnetization decreases more sharply with increasing temperature. These results are consistent with those obtained by Nagata et al [12]. Fig.…”

Low-field magnetic entropy changes in Hf1−XTaXFe2

“…It is clearly seen that the magnetization decreases abruptly at the transition temperature, 196 K and 260 K for X = 0.18 and 0.155, respectively, indicating a FOMT from F to AF state. This result is consistent with that obtained by Nagata et al [14]. With increasing Ta content, the magnetization decreases more sharply with increasing temperature.…”

Structure and unusual magnetic properties in the itinerant electron system Hf0.8Ta0.2(Fe1−xCox)2

“…The magnetic properties of Laves phase compounds of AB 2 -type, where A is a transition metal and B is iron, have been extensively investigated [1][2][3][4][5]. This kind of compounds crystallizes in the MgZn 2 -type structure (C14 phase), in which the A atom occupies the 4f site, whereas the B1 atom occupies the 2a site and the B2 atom the 6h site.…”

“…The magnetization and transport properties of the itinerant electron system Hf 1−x Ta x Fe 2 were focused on by many researchers in recent years [3][4][5]. The magnetic ground state changes from ferromagnetic (FM) to antiferromagnetic (AFM) at a Ta concentration of about x c ≈ 0.3.…”
