摘要：
A cryostat for measuring the resistivity, magnetoresistivity and Hall coefficient of thin metallic films is described. The cryostat, which is designed to operate between 1.4 and 273 K, is mounted in a 30 mm gap between the poles of an iron-core electromagnet, capable of reaching 1.5 T. Liquid helium consumption is low (≈ 0.5 dm3 h-1). The cryostat is specifically designed for manufacture in a non-specialist workshop. © 1990.
