(LBMO)powder synthesized by the sol-gel method.The experimental results showed that with increasing W dopant
the resistivity increases.The experiment also showed that doping W can gradually increase the room temperature magnetoresistance of the material.When x=0.1
magnetoresistance at room temperature reaches 11.5%
which is increased by 100%
compared with pure LBMO under the same condition
which provides the experimental proof for the magnetoresistance device research.
