The Phase Relations of the Co-Ni-In Ternary System at 673 K and 873 K and Magnetic Properties of Their Compounds

The phase relationships of the ternary Co-Ni-In system at 673 K and 873 K were investigated by means of powder X-ray diffraction, scanning electron microscopy equipped with energy dispersive spectroscopy, and optical microscopy. Though CoIn<sub>2</sub> does not exist at 873 K, the ternar...

description The phase relationships of the ternary Co-Ni-In system at 673 K and 873 K were investigated by means of powder X-ray diffraction, scanning electron microscopy equipped with energy dispersive spectroscopy, and optical microscopy. Though CoIn<sub>2</sub> does not exist at 873 K, the ternary solid solution Co<sub>1−x</sub>Ni<sub>x</sub>In<sub>2</sub> exists at both 673 K and 873 K with different composition ranges. The Rietveld refinements were carried out to investigate the crystal structure of Co<sub>1−x</sub>Ni<sub>x</sub>In<sub>2</sub> (x = 0.540, and 0.580) and Ni<sub>2−x</sub>Co<sub>x</sub>In<sub>3</sub> (x = 0.200). The magnetization dependence of temperature (MT) curves of Ni<sub>2−x</sub>Co<sub>x</sub>In<sub>3</sub> (x = 0.200) and Co<sub>1−x</sub>Ni<sub>x</sub>In<sub>2</sub> (x = 0.540) are similar to those of the ferromagnetic shape memory alloys Ni-Mn-A (A = Ga, Sn, and In), but do not undergo martensitic transformation. The maximum magnetic entropy changes in Ni<sub>2−x</sub>Co<sub>x</sub>In<sub>3</sub> (x = 0.200) and Co<sub>1−x</sub>Ni<sub>x</sub>In<sub>2</sub> (x = 0.540) under 3T are 1.25 and 1.475 J kg<sup>−1</sup>K<sup>−1</sup>, respectively.
