✦ Synopsis

The behaviour of some metal foil strain gauges in magnetic fields up to 6 T at room temperature and at the boiling points of nitrogen and helium has been investigated. At room temperature the Constantan alloy gauges showed a significant magnetically induced negative zero shift. Although at room temperature and liquid nitrogen temperature the Karma-type alloy gauges tested showed no observable magnetoresistance, they all showed a significant positive magnetoresistance at liquid helium tempera ture.

A simple theoretical model that describes the pulsed Davies electron-nuclear double resonance (ENDOR) experiment for an electron spin S ‫؍‬ 1 2 coupled to a nuclear spin I ‫؍‬ 1 2 was developed to account for unusual W-band (95 GHz) ENDOR effects observed at low temperatures. This model takes into a
