摘要：

Magnetoresistance (MR) as large as 70000% at H=12T has been observed in bulk (La3/4Tb1/4)(2/3)Ca1/3MnO3 at T-c approximate to 100K, the temperature at which the compound becomes ferromagnetic. This unusual effect is accompanied by magnetovolume effects above T-c which vanish rapidly below T-c. This fact along with the shape of the isotherms above and below T-c suggest two different mechanisms for the giant MR above and below T-c.
