In order to solve the problems of the low solubility of magnetic ions in III-V semiconductors and the difficulty of the carrier control in II-VI semiconductors, modulation-doped III-V/II-VI superlattice structures have been proposed (Kamatani and Akai 2001a). Here, a... [Pg.76]

III- V barrier layers, where impurities are incorporated, provide carriers to II-VI magnetic layers. The results of the first principle calculation for a AlAs C/(Cd,Mn)Te superlattice shows that the ferromagnetic state is indeed stable for high concentrations of C. [Pg.76]

Magnetic rare-earth superlattices R/M (M = Y, Lu) behave in a variety of ways. Two remarkable features in these artificial structures are (i) helical magnetic order is found to... [Pg.158]

Magnetoelastic stress isotherms cra and crb of the H040/LU 15)50 superlattice, clamped along the a and b axes of the hep structure, respectively, and with the applied magnetic field along the easy b axis are presented in fig. 59 (Del Moral et al. 1998). The sudden... [Pg.159]

Fig. 60. The variation of the basal plane cylindrical symmetry breaking magnetoelastic stress, Af p, at 10 K and at an applied magnetic field of 12 T, multiplied by (/iho + nLu)< as a function of n o (where ho and n y are the number of atomic planes in the Ho and Lu blocks, respectively) for (Ho /Lu 15)50 superlattices. The line indicates the fitting by the theoretical model. After Del Moral et al. (1998). Fig. 60.
