摘要：

The ER-effect in LCMO near the phase separation regime at x = 0.48 (Ca-content) is discussed in the framework of metallic/insulating layer sequences attached to internal boundaries. For x=0.51. in particular, we find evidence for a natural spin transistor-like action based on the involvement of charge order stripe domains, which are characteristic for LCMO if x > 0.5.
