The mechanism of Tc performance for Zn doped MgB2 sintered in magnetic field
The mechanism of magnetic field sintering on the critical transition temperature, Tc, for the Zn doped MgB2 superconductor was investigated with the observation of Raman scattering measurement and the Raman spectra fit analysis. The broadened E2g 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 E2g mode and the Tc.
