| 中文摘要 | Magnetic properties of Nd0.5Ca0.5Mn0.98Ga0.02O3 were investigated systematically through magnetization and electron spin resonance (ESR) measurements. It was found that substituting 2% Mn with Ga reduces the charge ordering temperature and induces an additional peak in the magnetization-temperature curve at about 45 K. The magnetization and ESR measurements suggest that the spin-glass-like phase induced by doping Ga at Mn sites and antiferromagnetic charge-orbital-ordered phase coexist at low temperature, the paramagnetic phase and antiferromagnetic phase coexist when the temperature is between the Neel temperature and the charge-ordering temperature.
