3d transition-metal high-entropy Invar alloy developed by adjusting the valence-electron concentration
Rao, Ziyuan; Çakır, Aslı; Özgün, Özge; Ponge, Dirk; Raabe, D.; Li, Zhiming; Acet, Mehmet (American Physical Society, 2021)By considering the valence-electron concentration of 3d transition-metal alloys and compounds, we develop 3d high-entropy alloy Mn12.1Fe34.2Co33.5Ni12.3Cu7.9 with 8.7 electrons per atom, which is identical to that of ... -
Emergence of net magnetization by magnetic field biased diffusion in antiferromagnetic L10 NiMn
Çakır, Aslı; Josten, Nicolas; Noorzayee, Sakia; Miroshkina, Olga; Zingsem, Benjami (AMER PHYSICAL SOC, 2023)NiMn is a collinear antiferromagnet with high magnetocrystalline anisotropy (K = -9.7 x 105 J m-3). Through magnetic annealing of NiMn with excess Ni, strongly pinned magnetic moments emerge due to an imbalance in the ... -
Formation of precipitates in off-stoichiometric Ni-Mn-Sn Heusler alloys probed through the induced Sn-moment
Eggert, Benedikt; Çakır, Aslı; Günzing, Damian; Josten, Nicolas; Scheibel, Franziska; Acet, Mehmet (Royal Society of Chemistry, 2023)The shell-ferromagnetic effect originates from the segregation process in off-stoichiometric Ni-Mn-based Heusler alloys. In this work, we investigate the precipitation process of L21-ordered Ni2MnSn and L10-ordered NiMn ... -
Magnetic properties of fcc and ? phases in equiatomic and off-equiatomic high-entropy Cantor alloys
Özgün, Özge; Koch, David; Çakır, Aslı (AMER PHYSICAL SOC, 2023)The equiatomic face-centered-cubic (fcc) high-entropy alloy CrMnFeCoNi has a valence electron concentra-tion of 8 electrons per atom, equivalent to that of Fe. Its ground-state properties are similar to that of fcc-Fe and ... -
Magnetic properties of the FCC and BCC phases of (MnFeCoNi)(80)Cu(20_x)Z(x()Z(1)& nbsp;Al, Ga) high-entropy alloys
Orbay, Yaşar; Rao, Ziyuan; Çakır, Aslı; Tavşanoğlu, Tolga; Farle, Michael; Acet, Mehmet (PERGAMON-ELSEVIER SCIENCE LTD, 2023)In this work, the FCC-BCC phase transition in (MnFeCoNi)80Cu20 (Al, Ga) high entropy alloys were investigated on the basis of structural, magnetic, hardness and thermal expansion properties. It is found that the equiatomic ...
