摘要：

The effect of Ti doping in Bi(0.3)Ca(0.7)Mn(1-x)TixO(3) (where x = 0.0, 0.015, 0.03, 0.05, 0.08, 0.12 and 0.16) on structural, magnetic and transport properties have been studied. The charge-ordering temperature (T-CO) decreases gradually with increasing Ti doping content, and finally disappears completely for x = 0.12. The Neel temperature (T-N) also decreases with increasing Ti doping content. A transition to a cluster glass like state is observed at T <= T-N. The zero field cooled/field cooled (ZFC/FC) magnetization decreases at high temperature (T > 200 K) with increasing Ti content, whereas an opposite trend is observed at low temperature (T < 200 K). Small exchange bias effect is also observed for x = 0.08 at 10 K. The resistivity increases with increasing Ti doping content. The disorder induced by Ti doping on the Mn site plays a key role in explaining the observed magnetic and electrical properties.
