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 ...
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 ...
Annealing-time and annealing-temperature dependencies of the size of Ni-Mn-In shell-ferromagnetic nano-precipitates by Scherrer analysis
(Amer Inst Physics, 2018)
Shell-ferromagnetic effects are observed in Ni-Mn-based off-stoichiometric Heuslers decomposed into ferromagnetic precipitates embedded in an antiferromagnetic matrix when the surface-to-volume ratio of the precipitates ...
Evidence for the formation of nanoprecipitates with magnetically disordered regions in bulk Ni50Mn45In5 Heusler alloys
(Amer Physical Soc, 2019)
Shell ferromagnetism is a new functional property of certain Heusler alloys which was recently observed in Ni50Mn45In5. We report the results of a comparative study of the magnetic microstructure of bulk Ni50Mn45In5 Heusler ...
Emergence of net magnetization by magnetic field biased diffusion in antiferromagnetic L10 NiMn
(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
(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 the FCC and BCC phases of (MnFeCoNi)(80)Cu(20_x)Z(x()Z(1)& nbsp;Al, Ga) high-entropy alloys
(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 ...
