摘要：

Mixed ferromagnetic ( FM) and antiferromagnetic ( AFM: A-type and CE-type) phases and anomalous lattice parameters have been observed around 50 K in ( La1-yPry) 0.65Ca0.35MnO3 ( y = 0.5-0.65) from neutron diffraction studies. The critical magnetic field is profoundly increased by Pr doping. Field-dependent and temperature-dependent magnetization M( H, T) and the hysteresis behaviour of resistivity indicate the presence of magnetostriction and mixed magnetic phases. The step-like behaviour of M( H) data around 5 K is attributed to the martensitic transition, which is found to be related to the CE-type AFM phase in the system.
