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 J rs more than hard SD J rs , so that it may be effective in removing soft secondary NRM components. The domain...
