Colossal magnetoresistance manganites: a laboratory for electron–phonon physics

Abstract
It is argued that the ‘colossal’ magnetoresistance rare earth manganites present an unusual opportunity for condensed matter physics because they are metals in which the electron–lattice interaction is both unusually strong and tunable; i.e. variable over a wide range by variation of chemical composition, strain, magnetic field and temperature. The variability will allow systematic and controlled study of properties of electrons strongly coupled to phonons.
