  We classify division algebras that are principal Albert isotopes of cyclic
Galois field extensions of degree $n>2$ up to isomorphisms. We achieve a
"tight" classification when the cyclic Galois field extensions is cubic. The
classification is "tight" in the sense that the list of algebras has features
that make it easy to distinguish non-isomorphic ones. Rough classification
results on regular algebras that are principal Albert isotopes of Galois
$C_n$-algebras are obtained as well; the principal Albert isotopes of
$C_3$-Galois algebras are again classified up to isomorphisms.
