Abstract

In this paper we present the results of measurements of the microwave surface impedance of a powder sample and two films of MgB₂. The powder sample has a T_c = 39 K and the films have T_c = 29 K and 38 K. These samples show different temperature dependences of the field penetration depth. Over a period of six months, the film with T_c = 38 K degraded to a T_c of 35 K. We compare the results on all samples with data obtained elsewhere and discuss the implications as far as is possible at this stage.
