Abstract
The infrared absorption of charge density waves coupled to a magnetic background is first observed in two manganites La1-xCaxMnO3 with x = 0.5 and x = 0.67. In both cases a BCS-like gap 2 Delta (T), which for x=0.5 follows the hysteretic ferro-antiferromagnetic transition, fully opens at a finite T0 < TNeel, with 2 Delta(T0)/kTc close to 5. These results may also explain the unusual coexistence of charge ordering and ferromagnetism in La0.5Ca0.5MnO3.
