Abstract: We study the magnetic entropy behavior in Gd₅₅Al₂₀Ni₁₂Co₁₀Mn₃ metallic glass by magnetic susceptibility, resistivity, and specific heat at low temperatures. The Gd-based metallic glass shows metallic behavior, and a ferromagnetic to paramagnetic transition at 106 K. The ferromagnetic order assists the electron-phonon coupling, which induces the large excess magnetic entropy below Curie temperature in the Gd-based metallic glass. The results are important to understand the electron-phonon coupling behavior in disordered alloys.
