Abstract
The magnetic behavior of La1-xSrxCuO2.5 has been investigated by means of m uon spin relaxation (mu SR). The Neel temperatures T-N for several Sr conce ntrations (0.0 less than or equal to x less than or equal to 0.20) have bee n measured. We found that T-N is about 125 K in the insulating region, and 10-15 K in the metallic region, suggesting that the hole carriers are local ized in the insulating region and delocalized in the metallic region.
