Abstract

The mechanism of magnetic field sintering on the critical transition temperature, T_c, for the Zn doped MgB₂ superconductor was investigated with the observation of Raman scattering measurement and the Raman spectra fit analysis. The broadened E_2g mode in Raman spectra shows the strengthening of the electron–phonon coupling (EPC) for the sample sintered in magnetic field. A synchronous fluctuation is observed between the Raman characters of the E_2g mode and the T_c.
