摘要：

The La0.7Sr0.3MnO3 perovskite is a ferromagnetic half-metal with a strong spin polarization and high Curie temperature T-C (355 K). We have shown that a combination of the break junction technique with the special properties of the La0.7Sr0.3MnO3 perovskite can lead to extremely high values of tunneling magnetoresistance ratio (> 10(3)%) and high field sensitivity (30%/Oe). These results are obtained in magnetic fields below 1 kOe and at room temperature.
