Title: | Large magnetic entropy and electron-phonon coupling in Gd-based metallic glass | Authors: | Tang, MB Xia, L Chan, KC Zhao, JT |
Issue Date: | 1-Dec-2012 | Source: | Journal of applied physics, 1 Dec. 2012, v. 112, no. 11, 113503, p. 1-5 | 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. | Keywords: | Aluminium alloys Cobalt alloys Curie temperature Electron-phonon interactions Gadolinium alloys Magnetic susceptibility Manganese alloys Metallic glasses Nickel alloys Specific heat |
