Ferromagnetism: Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample Scanning electron microscope: A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.Alloy: A mixture of metallic elements or compounds with other metallic or metalloid elements in varying proportions.SQUID: Superconducting quantum interference device.Neutron diffraction studies are needed to understand the degree of ordering and the stabilization conditions of the B2 phase. The degree of B2 ordering is known to affect TC of B2 FeCo so that a similar situation can be expected for the compound investigated in this work. The present results indicate that TC increases as the temperature is cycled sequentially with the sample being exposed to elevated temperature for the time interval of the M(T) experiments taking place at 4 K min-1. This would depend on the time and temperature at which the annealing is carried out. The authors have prepared a multi-component B2 compound starting with the high-entropy alloy MnFeCoNiCu and adding 25 at.% Al. The authors carried out X-ray diffraction (XRD) measurements at room temperature using Cu K-alpha radiation. The authors carried out a further homogenization for 5 days at 1273 K and quenched the sample in water at room temperature. The authors prepare and examine here the structural and in particular the magnetic properties of the ordered B2 (MnFeCoNiCu)3 Al compound expecting a magnetic moment of about 0.8 μB from the Slater-Pauling rule. The substitution of one of the elements in a 3d high-entropy alloy by Al tends to form mixed FCC-BCC phases with the BCC phase exhibiting B2 ordering in some cases. Such a multi-component alloy did indeed show features related to Invar properties in the thermal expansion, magnetization, and elastic modulus. Indeed, the authors had shown that the Cantor alloy possesses the predicted room-temperature properties of anti-Invar FCC-Fe. future: Neutron diffraction studies are needed to understand the degree of ordering and the stabilization conditions of the B2 phase.įrom the electronic aspect, the Cantor alloy is equivalent to FCC-Fe.what: The authors show the results of EDX mapping in Fig 2. ![]() who: Aslu0131 u00c7aku0131r from the Department of Metallurgical and Materials Engineering, Muu011fla Su0131tku0131 Kou00e7man University, Muu011fla, Turkey have published the paper: A High-Entropy B2 Heusler Alloy, in the Journal: (JOURNAL).
