摘要：

Using a contact-less microwave technique, we have identified a phase transition in small crystals of La1.8Sr0.2NiO4-delta. This transition is coincident with a weak diamagnetic response, most likely to a superconducting state. The transition region is very broad, with a width approximately 70 K. The temperature-dependent shape of the transition is accurately described by a model which describes a network of small superconducting regions connected by weak links.
