摘要：

The enhancement of room temperature magneto resistance can be induced by the Ti substitution for Mn in La0.67Sr0.33Mn1-xTxO3, which may be connected with the shift of the Curie temperature from a high temperature to the near room temperature by the Ti substitution. This experimental observation may provide a route to improve CMR behavior of the perovskite manganites at room temperature. (C) 2002 Elsevier Science B.V. All rights reserved.
