With the aim of probing the effect of magnetic disorder in the low-temperature excitations of manganites, specific heat measurements were performed in zero field, and in magnetic fields up to 9 T in polycrystalline samples of La 0:72x Y x Ca 0:3 MnO 3 ; with Y concentrations x ¼ 0; 0.10, and 0.15. Y
