Maafa I, Hajjar-Garreau S, Jaafar R, Berling D, Pirri C, Mehdaoui A, Denys E, Florentin A, Garreau G.
PMID: 23740804
J Phys Condens Matter. 2013 Jun 26;25(25):256007. doi: 10.1088/0953-8984/25/25/256007. Epub 2013 Jun 06.

We report on the first all-epitaxial ferromagnet/inorganic semiconductor/ferromagnet hybrid heterostructure that exhibits (i) a Ge barrier of diamond crystal structure, (ii) room-temperature ferromagnetic electrodes and (iii) very smooth interfaces. Both bottom- and top-Fe-Ge electrodes exhibit tiny in-plane magnetic anisotropies...
