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 ΒΌ 0; 0.10, and 0.15.

The investigation of the manganites La 2=3 2 x Pr x Sr 1/3 MnO 3 , La 2/3 Sr 1=3 2 x Ca x MnO 3 and La 2=3 ΓΎ x Ca 1=3 2 2x Ag x MnO 3 , which all exhibit Mn 3ΓΎ :Mn 4ΓΎ ΒΌ 2, shows that it is possible to reach high magnetoresistance at room temperature, up to 21% under 1.2 T.
