Application of the Faraday Method to Magnetic Measurements under Pressure

Abstract

Weak static magnetic moments have been measured under hydrostatic pressure up to 20 kilobars with the full sensitivity of the Faraday method over a wide temperature range. Only minor modifications of the magnetometer and cryogenic equipment are needed to accommodate a miniature pressure clamp. The method is simple, at least two orders of magnitude more sensitive than previous techniques, and makes Pauli paramagnets and dilute magnetic alloys accessible to magnetic measurements under high pressure.
