A process for the spatially resolved temperature monitoring, suspension of ferromagnetic microparticles and use of these suspension

摘要

For monitoring the temperature is a body (1) a ferromagnetic substance (2), the curie - temperature corresponds to a desired temperature limit value. By means of an mr - measurement, a spatially resolved representation of the body (1) is obtained, wherein artifacts, which in the ferromagnetic state of the substance to be caused, be used as a criterion for this purpose, that the temperature limit value is not yet reached.
