TL;DR: The magnetic-field-induced shape recovery of a compressively deformed NiCoMnIn alloy is reported, attributing this deformation behaviour to a reverse transformation from the antiferromagnetic (or paramagnetic) martensitic to the ferromagnetic parent phase in the Ni45Co5Mn36.7In13.3 single crystal.
Journal ArticleDOI
Metamagnetic shape memory effect in a Heusler-type Ni43Co7Mn39Sn11 polycrystalline alloy
Ryosuke Kainuma,Y. Imano,Wataru Ito,Haruhiko Morito,Yuji Sutou,Katsunari Oikawa,Asaya Fujita,Kiyohito Ishida,Satoshi Okamoto,Osamu Kitakami,Takeshi Kanomata +10 more
TL;DR: In this article, shape memory and magnetic properties of a Ni43Co7Mn39Sn11 Heusler polycrystalline alloy were investigated by differential scanning calorimetry, the sample extraction method, and the three-terminal capacitance method.
Journal ArticleDOI
Martensitic and Magnetic Transformation Behaviors in Heusler-Type NiMnIn and NiCoMnIn Metamagnetic Shape Memory Alloys
TL;DR: In this paper, the authors investigated the martensitic and magnetic transformation behaviors of Ni50MnIn, Ni45Co5MnIN, and Ni42.5Co7.5mnIn alloys by differential scanning calorimetry (DSC), vibrating sample magnetometry (VSM), and transmission electron microscopy (TEM).
Journal ArticleDOI
Observation of large magnetoresistance of magnetic Heusler alloy Ni50Mn36Sn14 in high magnetic fields
Keiichi Koyama,Hironari Okada,Kazuo Watanabe,Takeshi Kanomata,Ryosuke Kainuma,Wataru Ito,Katsunari Oikawa,Kiyohito Ishida +7 more
TL;DR: In this article, the magnetic and electrical properties on magnetic Heusler alloy Ni50Mn36Sn14 were studied in magnetic fields up to 18T in 4.2-270k temperature range.
Journal ArticleDOI
Effect of magnetic field on martensitic transition of Ni46Mn41In13 Heusler alloy
Katsunari Oikawa,Wataru Ito,Y. Imano,Yuji Sutou,Ryosuke Kainuma,Kiyohito Ishida,Satoshi Okamoto,Osamu Kitakami,Takeshi Kanomata +8 more
TL;DR: In this article, a unique martensitic transition from the ferromagnetic austenite phase to the antiferromagneticlike martensite phase was detected and magnetic-field-induced reverse transition was confirmed in a high magnetic field.
