Abstract / Description:We present the first results of Raman scattering with application of
magnetic field on magnesium diboride (MgB2). In this work, we have
investigated the magnetic field dependence of the 72 meV (E-2g mode)
and the pair-breaking peak around 100 cm(-1) which corresponds to
sigma-band gap. Intensity enhancement of Raman features around 800
cm(-1) accompanied with broadening in the line shape of E-2g mode has
been observed in some polycrystalline samples at 0 GPa. Results are
compared with previous Raman study under hydrostatic pressure. (c) 2006
