They did it:

MORDEN S.J. (1992) The magnetic properties of the Millbillillie eucrite:
Palaeointensity results and evidence for a dynamo-type magnetising field
(Meteoritics 27-3, 1992, A264):

The palaeointensity results indicate that the rock cooled in a strong
magnetic field; an internal dynamo-type magnetising field is preferred
over external fields (solar wind or impact-generated) for dynamical
reasons. On the assumption that a body similar to 4 Vesta is the
Howardite-Eucrite-Diogenite parent body, the high palaeointensity
results could argue for an iron core for such a body.
