Abstract: Heterointerfaces are the basic building blocks for many electronic devices, most of which interfaces are formed between materials with ordered atomic lattices but non-ordered charges or spins. For next generation electronic devices which can offer ?more than Moore?, however, interfaces involving collective behaviour or ordered phase of charges / spins will become increasingly important. In this context, we have studied the interaction between materials with different order parameters such as superconductor, ferromagnet, and antiferromagnet, in the form of either direct contact or coupling across ultrathin non-magnetic materials. Several interesting and novel phenomena, such as CAR effect at SC-DW interface, instability of exchange bias induced by superconductor, suppression of superconductivity by AFM and oscillation of coupling between conventional superconductors, have been observed and discussed by using appropriate theoretical models. We hope that this work will open new opportunities for studying electromagnetic interactions at interfaces between materials with different order parameters.
