Abstract
The surface-boundary magnetization (MSB) for a manganese perovskite La0.7Sr0.3MnO3 has been investigated using spin-resolved photoemission spectroscopy, which has an ∼5Å probing depth. MSB shows the full moment at very low temperature but decays much faster than the bulk magnetization (MB) upon heating. This result provides direct insight into various novel properties at grain and surface boundaries observed in the polycrystalline samples and junctions of manganese perovskites. © 1998 The American Physical Society.
