Shell-ferromagnetism and decomposition in off-stoichiometric Ni50Mn50-xSbx Heuslers
(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 ...
Magnetic proximity effect and shell-ferromagnetism in metastable Ni50Mn45Ga5
(Amer Inst Physics, 2016)
The present study on magnetic and structural properties of Ni(50)Mn(45)G(a)5 confirms that structural metastability is an inherent property of Ni50Mn50-xXx Heusler alloys with X as In, Ga, and Sn. The ternary alloy transforms ...
Investigation of temperature dependent magnetization and elastic modulus in Si-doped Fe65Ni35 invar alloys
(Elsevier Science Sa, 2017)
Fe-65 Ni-35 invar is a prominent nickel steel alloy exhibiting low coefficient of thermal expansion around room temperature. The present work deals with the temperature dependence of the elastic modulus and magnetization ...
Non-volatile high-temperature shell-magnetic pinning of Ni-Mn-Sn Heusler precipitates obtained by decomposition under magnetic field
(Elsevier Science Bv, 2018)
The thermodynamic instability of the off-stoichiometric Ni49.8Mn45.1Sn5.1 martensitic Heusler causes it to decompose into ferromagnetic Ni50Mn25Sn25 precipitates and an antiferromagnetic NiMn matrix. If the decomposition ...
Magnetic and structural instabilities in mictomagnetic Cu50Mn45Al5 against the formation of ferromagnetic precipitates
(Pergamon-Elsevier Science Ltd, 2020)
A new property of Heusler alloys known as shell-ferromagnetism is observed predominantly in NiMn-based Heusler alloys with X as Ga, Al, In and Sn. An antiferromagnetic-matrix/shell-ferromagnetic precipitate dual-phase ...
A variable pole magnet
(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 ...
Room-temperature five-tesla coercivity of a rare-earth-free shell-ferromagnet
(American Institute of Physics Inc., 2017)
Ni2MnX-based Heusler (X: main group element), when enriched with Mn, will decompose into ferromagnetic Ni2MnX and antiferromagnetic NiMn when temper-annealed around 650 K. When the starting material is chosen such that the ...
Decomposition in Ni-Co-Mn-In functional Hensler alloys and its effect on shell-ferromagnetic and magnetocaloric effects
(Amer Physical Soc, 2020)
Ni-Co-Mn-In Heusler-based compounds are interesting for their magnetocaloric properties and have been widely investigated for this purpose. For Co compositions more than 5 at% in (Ni100-xCox)(50)Mn25+yIn25-y the material ...
Ab initio Prediction of Martensitic and Intermartensitic Phase Boundaries in Ni-Mn-Ga
(Amer Physical Soc, 2016)
Despite the importance of martensitic transformations of Ni-Mn-Ga Heusler alloys for their magneto-caloric and shape-memory properties, the martensitic part of their phase diagrams is not well determined. Using an ab initio ...
Segregation tendency of Hensler alloys
(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 ...
