摘要
We present electrical, magnetic and crystal structure for a series of La1.2(Sr1.8-xCax)Mn2O7 (x = 0-0.8) manganites. The sample of x = 0.4 exhibits the highest magnetoresistance (MR) ratio [ρ(H)-ρ(O)/ρ(H)]×100% of -108% at the temperature of 102 K. The Curie temperature (TC) decreases from 135 K for x = 0-102 K for x = 0.4. The hysteresis phenomenon was observed when the temperatures were lower than the magnetic transition temperature. The static strain within the compound for x = 0.4 has also been found by high-resolution transmission electron microscopic techniques.
