Abstract

The investigation of the spin and quasiparticle relaxation dynamics in LMCO and LMO single crystals and thin films was discussed. It was suggested that quasiparticle relaxation rate is governed by the temperature and magnetic field dependent pseudogap in LCMO and by the temperature independent Jahn-teller distortion gap in LCMO. It was observed that the magnetic field induced increase of spectral weight in the pseudogap affects both the quasiparticle and spin relaxation dynamics in LCMO. The result shows that the coupled dynamics of the charge, spin and lattice is strongly correlated with distinct gap structures in these manganites.
