Abstract

The effects of Ge partial substitution onto Si site of Er₅Si₄ alloy were investigated by means of thermal and electrical transport measurements. Temperature-dependent electrical resistivity (ρ), Seebeck coefficient (S), and thermal conductivity (κ) measurements from 7 to 300 K were performed on a series of Er₅Si_4-xGe_x alloys with x varying from 0 to 2. Noticeable anomalies were observed at the magnetic phase transition in Er₅Si₄ alloy in these transport measurements. It was also found that the resistivity of Er₅Si_4-xGe_x alloys gradually increases and the Curie temperature T_C decreases upon replacing Si with Ge. No sign of anomalous feature was detected in Er₅Si₂Ge₂, indicating that the magnetic phase transition may be suppressed at this substitution level.
