Segregation tendency of Hensler alloys
Sokolovskiy, V. V.; Gruner, M. E.; Entel, P.; Acet, M.; Çakır, Aslı; Baigutlin, D. R.; Buchelnikov, D. (Amer Physical Soc, 2019)Segregation in a series of Ni2Mn1+x(In, Sn, Ga, Al)(1-x) and Mn2Ni1+x(Ga, Al) as well as Ni2+xMn1-xGa Heusler alloys is studied by first-principles calculations. We show that Mn-rich Ni2Mn1+x(In, Sn, Al)(1-x) compounds are ... -
Shell-ferromagnetism and decomposition in off-stoichiometric Ni50Mn50-xSbx Heuslers
Wanjiku, Z; Çakır, Aslı; Scheibel, F; Wiedwald, U; Farle, M; Acet, M (Amer Inst Physics, 2019)Off stoichiometric Heuslers in the form Ni(50)Mn(50-x)Z(x), where Z can be a group 13-15 element of the periodic system, decompose at about 650 K into a ferromagnetic full Heusler Ni(50)Mn(25)Z(25) and an antiferromagnetic ... -
Shell-ferromagnetism in a Ni-Mn-In off-stoichiometric Heusler studied by ferromagnetic resonance
Scheibel, Franziska; Spoddig, Detlef; Meckenstock, Ralf; Çakır, Aslı; Farle, Michael; Acet, Mehmet (Amer Inst Physics, 2017)Next to the multifunctional properties of Ni-Mn-based Heusler alloys new functionalities related to shell-ferromagnetism are emerging. To understand in more detail the properties of shell-ferromagnetism we examine a ... -
Shell-ferromagnetism in Ni-Mn-based Heuslers in view of ductile Ni-Mn-Al
Çakır, Aslı; Acet, Mehmet (Amer Inst Physics, 2017)The presentwork deals with magnetic and structural phase instabilities in Ni-Mn-based Heusler alloys especially Ni-Mn-Al. The temper-annealed Ni50Mn45Al5 Heusler alloy decomposes into the full stoichiometric Ni2MnAl and ... -
Shell-ferromagnetism of nano-Heuslers generated by segregation under magnetic field
Çakır, Aslı; Acet, M.; Farle, M. (Nature Publishing Group, 2016)We report on a new functional property in an AF martensitic Heusler Ni50Mn45In5, which when annealed at high temperatures under a magnetic field, segregates and forms Ni50Mn25In25 Heusler precipitates embedded in a Ni50Mn50 ... -
Transport properties of shell-ferromagnetic Heusler precipitates in decomposed Ni49.8Mn45.1Sn5.(1) and decomposition limit for Ni50Mn50-xSnx alloys
Çakır, Aslı; Koyun, Hatice Nur; Acet, Mehmet; Farle, Michael (Elsevier, 2020)Shell-ferromagnetism is observed in Mn-rich NiMn-based Heusler alloys as a result of phase-separation. Off-stoichiometric NiMn-based Heusler alloys decompose into a dual-phase composite when annealed under a magnetic field. ... -
A variable pole magnet
Çakır, Aslı; Krenke, Thorsten; Farle, Michael; Acet, Mehmet (Iop Publishing Ltd, 2018)The off-stoichiometric antiferromagnetic Heusler alloy Fe50Mn45Ga5 decomposes and forms ferromagnetic Fe50Mn25Ga25 precipitates embedded in an antiferromagnetic Fe50Mn50 matrix when temper-annealed at temperatures T > 550 ...
