ABSTRACT:
The invention relates to an organic material (5) usable in an electron paramagnetic resonance (EPR) magnetometer, as well as to a probe (3) using said material.
The object of the invention is to provide a material simultaneously having a limited line width (EPR), good temperature characteristics and which does not react in the presence of water.
This object is achieved with the aid of a radical cation salt of formula
