Trying to make a PostgreSQL field with a list of foreign keys in Django

Here is what I'm trying to do: Make a model in Django that is a PostgreSQL array (database specific type), which contains foreign keys to another model.

class Books(models.Model):
    authors = ArrayField(
        models.ForeignKey('my_app.Authors', default=None, null=True, blank=True),
        blank=True,
        default=list()
    )

When I try to makemigrations, Django gives me this error:

SystemCheckError: System check identified some issues:
ERRORS:
my_app.Books.authors: (postgres.E002) Base field for array cannot be a related field.

Any Ideas on how to beat that?
