Abstract

Summary form only given. Interesting properties and new phenomena are usually found in magnetically heterogeneous systems where different magnetic regions coexist and are magnetically coupled. For example, multilayered structures of some magnetic materials can present giant magnetoresistance and spin valve properties, exchange bias, or inverted hysteresis loops with negative remanence. In this work, we have studied the magnetic properties of ferrimagnetic/ferrimagnetic bilayers of the GdCo/GdCo amorphous system.
