  We investigate some physical characteristics of Millisecond Pulsar (MSP) such
as magnetic fields, spin periods and masses, that are produced by Accretion
Induced Collapse (AIC) of an accreting white dwarf (WD) in stellar binary
systems. We also investigate the changes of these characteristics during the
mass-transfer phase of the system in its way to become a MSP. Our approach
allows us to follow the changes in magnetic fields and spin periods during the
conversion of WDs to MSPs via AIC process. We focus our attention mainly on the
massive binary WDs (M > 1.0Msun) forming cataclysmic variables, that could
potentially evolve to reach Chandrasekhar limit, thereafter they collapse and
become MSPs. Knowledge about these parameters might be useful for further
modeling of the observed features of AIC.
