Query: Piezo-Magneto-Electric Effects in p-Doped Semiconductors   We predict the appearance of a uniform magnetization in strained three
dimensional p-doped semiconductors with inversion symmetry breaking subject to
an external electric field. We compute the magnetization response to the
electric field as a function of the direction and magnitude of the applied
strain. This effect could be used to manipulate the collective magnetic moment
of hole mediated ferromagnetism of magnetically doped semiconductors.
