Effect of Al doping on the magnetic and elastic properties of Fe65Ni35 Invar alloys
(Scientific Technical Research Council Turkey-Tubitak, 2019)
Invar alloys have great importance due to their low thermal expansion coefficient. The effect of Al doping on Fe65Ni35 Invar alloy was investigated by temperature-dependent magnetization and elastic modulus measurements. ...
Transport properties of shell-ferromagnetic Heusler precipitates in decomposed Ni49.8Mn45.1Sn5.(1) and decomposition limit for Ni50Mn50-xSnx alloys
(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. ...
Neutron diffraction and symmetry analysis of the martensitic transformation in Co-doped Ni2MnGa
(Amer Physical Soc, 2020)
Martensitic transformations are strain driven displacive transitions governing the mechanical and physical properties in intermetallic materials. This is the case in Ni2MnGa, where the martensite transition is at the heart ...
Shell-ferromagnetism in a Ni-Mn-In off-stoichiometric Heusler studied by ferromagnetic resonance
(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 ...
3d transition-metal high-entropy Invar alloy developed by adjusting the valence-electron concentration
(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 ...
Shell-ferromagnetism of nano-Heuslers generated by segregation under magnetic field
(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 ...
Exchange bias caused by field-induced spin reconfiguration in Ni-Mn-Sn
(Amer Physical Soc, 2016)
Exchange bias is observed in ferromagnetic/antiferromagnetic (FM/AF) layered stacks and in materials with neighboring ferromagnetic and antiferromagnetic granules. The latter is commonly observed in Ni-Mn-based martensitic ...
Large magnetocaloric effects in magnetic intermetallics: First-principles and Monte Carlo studies
(E D P Sciences, 2015)
We have performed ab initio electronic structure calculations and Monte Carlo simulations of frustrated ferroic materials where complex magnetic configurations and chemical disorder lead to rich phase diagrams. With lowering ...
Shell-ferromagnetism in Ni-Mn-based Heuslers in view of ductile Ni-Mn-Al
(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 ...
Characteristics of 5M modulated martensite in Ni-Mn-Ga magnetic shape memory alloys
(Amer Inst Physics, 2015)
The applicability of the magnetic shape memory effect in Ni-Mn-based martensitic Heusler alloys is closely related to the nature of the crystallographically modulated martensite phase in these materials. We study the ...
