Paper Abstract

Noise was studied in an MgB2 thin film grown on a SiN substrate, with a superconducting transition temperature, Tc, near 39K. At the mid-point of the transition and at 10Hz a noise spectral density Sv = 0.34nVHz1/2 was measured. The temperature noise, Kn , of the MgB2 film at different frequencies is compared to that of cuprate high temperature superconducting (HTS) thin films (with Tc ~ 90 K) used currently in transition-edge devices. Kn values predict that 2-D arrays of high performance infrared devices can be developed using MgB2.
