Abstract
The exchange coupling in sandwiches of layers of pure bce Mo and random bce Mo88Re12 embedded in an Fe matrix has been studied by the first-principles Green function technique. We have calculated up to 20 layers of the spacer material for the planes (100) and (110) and obtained oscillation periods. The exchange coupling amplitude and periodicity are analysed with respect t o two effects! (i) the interface orientation and (ii) the electronic topolo gical transitions (ETTs), resulting in an essential difference between the Fermi surfaces of Mo88Re12 and pure Mo.
