摘要
We have observed room temperature magnetoresistance (MR) in Fe-site-substituted Sr2FeMoO6 crystal with a double perovskite structure. These melt-grown crystals have few grain boundaries and show high conductivity (similar to 10(-3) Omega cm at 300 K), which is advantageous for a practical application. We will discuss the possible origin on the basis of the substituent concentration dependence and temperature dependence of the magnitude of the MR.
