摘要：

We have experimentally demonstrated that a magnonic crystal-an artificial magnetic structure for controlling propagation of magnetostatic waves-can be used as an extremely sensitive sensor for detecting magnetic fields. Functional characteristics of the sensor were studied at room temperature and in a normal noisy space without considering any magnetic shielding. (C) 2011 American Institute of Physics.
