Abstract

We briefly review the principles of a magnetic microcalorimeter x-ray detector and the requirements for fabricating an array of these sensors, which include a paramagnetic sensor fabricated with thin-film techniques. We discuss two methods for depositing an Er-doped Au sensor film and present magnetization measurements from 4-300 K in 5 T and near the detector''s operating temperature and field. The deposited sensor films studied to date deviate from expected values in bulk materials.
