Decomposition in Ni-Co-Mn-In functional Hensler alloys and its effect on shell-ferromagnetic and magnetocaloric effects
Şaşmaz, Merivan; Dreist, F.; Iglesias, I.; Çakır, Aslı; Farle, Michael; Acet, Mehmet (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 ... -
Extended investigation of intermartensitic transitions in Ni-Mn-Ga magnetic shape memory alloys: A detailed phase diagram determination
Çakır, Aslı; Righi, Lara; Albertini, Franca; Acet, Mehmet; Farle, Michael; Aktürk, Selçuk (Amer Inst Physics, 2013)Martensitic transitions in shape memory Ni-Mn-Ga Heusler alloys take place between a high temperature austenite and a low temperature martensite phase. However, intermartensitic transformations have also been encountered ... -
Kinetic arrest and exchange bias in L1(0) Ni-Mn-Ga
Cakir, Asli; Acet, Mehmet; Farle, Michael (Wiley-V C H Verlag Gmbh, 2014)Ni-Mn-Ga Heusler alloys are particularly interesting for their magnetic shape-memory properties. However, more recently, the observation of magnetic glass-like behavior in these alloys, particularly at low Ga concentrations, ... -
Magnetic properties of the FCC and BCC phases of (MnFeCoNi)(80)Cu(20_x)Z(x()Z(1)& nbsp;Al, Ga) high-entropy alloys
Orbay, Yaşar; Rao, Ziyuan; Çakır, Aslı; Tavşanoğlu, Tolga; Farle, Michael; Acet, Mehmet (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 ... -
Magnetic proximity effect and shell-ferromagnetism in metastable Ni50Mn45Ga5
Krenke, Thorsten; Çakır, Aslı; Scheibel, Franziska; Acet, Mehmet; Farle, Michael (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 ... -
Shell-ferromagnetism in a Ni-Mn-In off-stoichiometric Heusler studied by ferromagnetic resonance
Scheibel, Franziska; Spoddig, Detlef; Meckenstock, Ralf; Çakır, Aslı; Farle, Michael; Acet, Mehmet (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 ... -
Transport properties of shell-ferromagnetic Heusler precipitates in decomposed Ni49.8Mn45.1Sn5.(1) and decomposition limit for Ni50Mn50-xSnx alloys
Çakır, Aslı; Koyun, Hatice Nur; Acet, Mehmet; Farle, Michael (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. ... -
A variable pole magnet
Çakır, Aslı; Krenke, Thorsten; Farle, Michael; Acet, Mehmet (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 ...
