Double-exchange ferromagnets with their associated large magnetoresistance have recently been considered as candidates in magnetic storage applications. We review materials aspects of one compound family, La{sub 1{minus}x}Ca{sub x}MnO{sub 3}. There exist two distinct low temperature regimes; (i) ferromagnetic and metallic (x{lt}0.5) and (ii) charge-ordered and semiconducting (x{gt}0.5). We describe transport, magnetic, thermal and acoustic response in each regime. {copyright} {ital 1997 American Institute of Physics.}
