Abstract
A magnetic field probe, particularly for magnetic resonance applications, comprises: —a detector liquid that exhibits a nuclear magnetic resonance (NMR) line characterized by a chemical shift δ; —an electrically conductive structure surrounding the detector liquid for receiving therefrom a magnetic resonance signal; and —a container containing the detector liquid; —the detector liquid containing paramagnetic dopant means dissolved therein; —said NMR transition having an observable resonance frequency ω when the field probe is placed in an external magnetic field; and has orientation means for orienting the field probe in relation to a reference direction of said external magnetic field. The concentration cof said paramagnetic dopant means is selected in such manner that, when the field probe is placed into an external magnetic field Band oriented in a predefined manner with respect to said external magnetic field at a given temperature T, a temperature dependence ω'(T) of said resonance frequency is substantially zero.
