In the present work we have investigated the transport properties in a
number of samples with square antidot lattices of different periods. In
samples with lattice periods equal to 700
and 850 we have observed the
conventional low-field commensurability magnetoresistance peaks
consistent with the previous observations in GaAs/AlGaAs and samples
with antidot lattices. In samples with a 600 lattice period a new
series of well-developed magnetoresistance oscillations has been found
beyond the last commensurability peak which are supposed to originate from
periodic skipping orbits encircling an antidot with a particular number of
bounds.
