Abstract

The compression behaviour of Heusler compounds viz, Rh2MnZn, Rh2FeZn, Co2NbB, and Co2TaB has been studied using various equations of state, namely Tait equation, Murnaghan equation, Shanker's equation and Kholiya and Chandra equation. It has been observed that the Tait equation of state generally fits best for the compression behaviour of the chosen materials, followed by the Murnaghan equation of state, whereas Kholiya and Chandra, and Shanker's equations of state are less accurate. All Heusler compounds exhibit similar patterns in compression behaviour with decreasing volume and increasing pressure with a slight deviation that may be due to their crystal structure and chemical composition. The obtained results are found to be in good agreement with the available experimental values. The results of this study can provide valuable insights into the compressibility and mechanical properties of Heusler compounds, which can inform their potential applications in various fields, including energy harvesting, spintronics, and thermoelectric devices.
