Magnetic circular dichroism of zinc-blende-phase MnTe

Abstract

Synthesis. -Air-stable, solid, and polyfunctional aryl and heteroarylzinc pivalates are efficiently prepared by either magnesium insertion or Hal/Mg exchange followed by transmetalation with Zn(OPiv) 2. Alternative routes are the directed magnesiation using TMP-MgCl·LiCl followed by transmetalation with Zn(OPiv) 2 or, for very sensitive substrates, direct zincation by using TMP-ZnOPiv. These zinc reagents not only show excellent stability towards air, but they also undergo a broad range of reactions with electrophiles. -(MANOLIKAKES, S. M.; ELLWART, M.; STATHAKIS, C.

Photoemission Study of the Electronic Structure of Semiconducting Compounds

“…The x =1 limit of Cd 1-x MnxTe, namely, MnTe with the zinc-blende structure has been synthesized using MBE [17]. The Mn 3d states in MnTe appears to be localized, essentially the same as those in diluted Cd1-xMnxTe.…”

Magnetic Oxide Semiconductors

“…2(b) right). MCD is the difference of the absorption coefficients for two circularly polarized lights and is proportional to the energy derivative of the absorption coefficient [144] so that the MCD is the largest around the onset of the absorption. Accordingly, the MCD spectrum can identify the ferromagnetic origin because the ferromagnetic metal often shows a monotonous MCD spectrum [91].…”

Temperature Dependence of Energy Gap of Highly Concentrated Cd1-xMnxTe(0.6 < x ≤ 1.0) Epilayers

“…This means that effects associated with AF-SG (antiferromagnetic-spin-glass) transition cannot be easily investigated in the bulk. Recent progress in growing techniques of diluted magnetic semiconduction (MBE) enabled fabrication of materials in the entire concentration range, i.e., up to x = 1.0 [4,10]. In this communication we report on the energy gap variation with the temperature in Cd1-xMnxTe epilayers with Mn concentration ranging from x = 0.6 to x = 1.0 (i.e.…”

“…The results are interpreted in the frames of the model predicting that the exchange contribution to the band edge shift is proportional to the product of the magnetic susceptibility and the temperature. 4,10]. In this communication we report on the energy gap variation with the temperature in Cd1-xMnxTe epilayers with Mn concentration ranging from x = 0.6 to x = 1.0 (i.e.…”

“…These effects were observed in bulk CdMnTe [2][3][4], ZnMnTe [5], ZnMnSe [6,7] and CdMnS [8]. The exchange contribution to the energy gap reflects a correlation between spins of the magnetic ions [9,3,7] and, therefore, it is particularly important in concentrated alloys possessing magnetically ordered (spin-glass or antiferromagnetic) phases [1].…”
