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 ...
Morphology effect on electrochemical properties of doped (W and Mo) 622NMC, 111NMC, and 226NMC cathode materials
(Pergamon-Elsevier Science Ltd, 2020)
An investigation was carried out on layered Li(NixMnyCo1-x-y)O-2 (NMC) cathode active materials for Li-ion batteries to determine the effect of morphology on their electrochemical performances. The NMC active materials ...
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 ...
Sepiolite-PAN intercalation used as Si3N4 forming precursor
(Kluwer Academic Publ, 2001)
Silicon nitride (Si3N4) formation was investigated using sepiolite and polyacrylonitrile as silicon and carbon source, respectively. It was found that purified sepiolite could readily adsorb a sufficient amount of acrylonitrile ...
Fabrication and characterization of SmCo5/Nb ferromagnetic/superconducting hybrid thin films grown by RF magnetron sputtering technique
(Pergamon-Elsevier Science Ltd, 2017)
Ferromagnet/Superconductor (F/S) bilayer hybrids show exclusive states due to the mutual interaction between the superconductor and the underlying ferromagnetic substructures in micron scale. In this work, we aimed to ...
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 ...
