Query: Conductance through a Magnetic Domain Wall in Double Exchange System   The conductance through a magnetic domain wall is calculated for the double
exchange system as a function of energy and the width of the domain wall. It is
shown that when the carrier density is low enough, the blockade is almost
complete even for the smoothly varying spin configuration, i.e., large width of
the domain wall. This result is applied to the manganese oxides.
