The ferromagnetic transition temperatures have been measured on two bathes of perovskite manganese oxides such as (La1-xRx)2/3Ca1/3MnO3(R=Ce, Pr, Nd, etc.) and La2/3(Ca1-yCdy)1/3MnO3. It is found that the (La1-xRx)2/3Ca1/3MnO3 samples have obviously

Infrared (IR) transmittance spectra were measured for a series of samples with different particle sizes. Two extra absorption peaks appear when the average particle size of the samples is smaller than 60 nm; these peaks can be ascribed to the surface
