This is a collaborative effort between Lamont-Doherty                      Geological Observatory and UCSB to study the magnetic behavior of               pseudosingle domain particles.  The work will utilize magnetic                  measurements on individual particles coupled with domain                        observations.  The magnetic measurements will be extended from                  remanence measurements to weak field susceptibility and                         hysteresis determination.  The particular topics are the                        following:  1.  Additional tests of the existence of metastable                 single-domain like states in IRM(s), TRM and VRM.  2.  The                      relationship between temperature dependence of domain structure                 and the TRM blocking process.  3.  The physical nature of                       nucleation and pinning sites.  4.  The role of nucleation in                    determining the response of PSD material to AF demagnetization.                 The last topic will lead to the application of new ideas on                     behavior of PSD particles to the interpretation of NRM.
