Design of a vector magnetometer for three dimensional magnetization measurements — •Markus Kleinhans, Marco Halder, Christopher Duvinage, and Christian Pfleiderer — Physik-Department, Technische Universitaet Muenchen, 85748 Garching, Germany

In magnetically ordered systems, the fundamental order parameter is the magnetization which is, in general, a three dimensonal vector quantity. Conventional magnetometers, however, typically are limited to the projection of the moment along the applied magnetic field hence missing key informations of systems such as Ising ferromagnets in transvers fields [1]. We report the design of a bespoke set of pickup coils for a vibrating sample magnetometer allowing for the simultaneous determination of all three components of the magnetization for temperatures down to 3 K and in fields up to 9 T. We demonstrate the potential of this technique by studying the anisotropic ferromagnets Co and Nd₂Fe₁₄B .
