Abstract
The grain‐size dependent behavior of pyrrhotite during a magnetic LT‐transition at 34 K is suitable for granulometric purposes. Cycling down to liquid Helium temperature suppresses soft MD Jrs more than hard SD Jrs, so that it may be effective in removing soft secondary NRM components. The domain structure of large pyrrhotite grains changes from MD at room temperature to SD or PSD below the LT‐transition.Keywords
