AbstractWe review the properties of diluted magnetic semiconductor (DMS) thin films and multilayers, with special attention to their usefulness in magneto-optical device applications. We begin with the most widely studied DMS family, i.e., alloys of II-VI semiconductors involving Mn ions. Prospects and challenges are discussed for achieving II1-xMnxVI-based non-reciprocal devices; and for devices operating in the far infrared. We also consider the unique advantages which DMSs offer for probing the properties of semiconductor heterostructures. We then discuss ferromagnetic DMSs, including those based on the III-V semiconductor family. And we briefly review the status of hybrid ferromagnetic-semiconductor structures achieved through recent advances in epitaxy of new materials.

AbstractWe report the effect of chemical pressure on the ferromagnetic ordering of the recently reported n-type diluted magnetic semiconductor Ba(Zn$$_{1-x}$$ 1 - x Co$$_{x}$$ x )$$_{2}$$ 2 As$$_{2}$$ 2 which has a maximum $$T_C$$ T C $$\sim$$ ∼ 45 K. Doping Sb into As-site and Sr into Ba-site induces negative and positive chemical pressure, respectively. While conserving the tetragonal crystal structure and n-type carriers, the unit cell volume shrink by $$\sim$$ ∼ 0.3$$\%$$ % with 15$$\%$$ % Sr doping, but drastically increase the ferromagnetic transition temperature by 18$$\%$$ % to 53 K. Our experiment unequivocally demonstrate that the parameters of Zn(Co)As$$_{4}$$ 4 tetrahedra play a vital role in the formation of ferromagnetic ordering in the Ba(Zn,Co)$$_{2}$$ 2 As$$_{2}$$ 2 DMS.
