On cooling the compounds of the form La1-xMxMnO3-y (where M is divalent cation) show a large decrease in resistivity associated with a paramagnetic to ferromagnetic transition. This transition is known to produce a large negative magnetoresistance, the so-called colossal magnetoresistance (CMR), nea...
