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 ...
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 ...
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 ...
