Abstract
The magnetic properties and magnetocaloric effect (MCE) in the ternary intermetallic compound of EuAuGe have been investigated. The compound undergoes a second-order magnetic phase transition at its own Curie temperatures T C∼33 K. A large reversible table-like MCE has been observed from 1 to 40 K, which is related to the magnetic field-sensitive magnetic phase transition. For the magnetic field changes of 0–5 and 0–7 T, the maximum values of magnetic entropy change (\(-{\Delta } S_{\mathrm {M}}^{\max }\)) are evaluated to be 7.6 and 10.1 J kg−1 K−1, respectively; the corresponding relative cooling power (RCP) are 358 and 499 J kg−1. The present results indicate that the EuAuGe compound is a considerable candidate for low-temperature refrigeration.
