Ferromagnetism of manganese-doped InSb alloys

Magnetic cluster developement in In1−x MnxSb semiconductor alloys

“…The obtained values are in good agreement with earlier studies in the = (0 01 − 0 06)% Mn concentration range [6]. The substitution of In by Mn brings no signif- Fig.…”

“…1). The presence of both MnSb and Mn 2 Sb phases could be pointed out only by using synchrotron radiation, as previously shown by Novotortsev et al [6]. From the most intense MnSb line recorded by XRD measurements and using Scherrer's equation [7], = 0 9 λ β cos θ where λ represents the X-ray wavelength, β is the angular width at half-maximum intensity and θ the diffraction angle, it is possible to estimate the diameter d of the magnetic particles.…”

“…Ferromagnetism in In 1− Mn Sb ( ∼ 0 02) with T up to 20 K has been observed in films grown by Molecular Beam Epitaxy (MEB) [5]. Earlier studies on bulk In 1− Mn Sb, performed in the 0.01 0.06 concentration range [6], pointed out the presence in the investigated samples of an In 1− Mn Sb solid solution with T C < 10 K and also microinclusions of manganese antimonide phase. These microinclusions (clusters) might be identified as either ferromagnetic MnSb or Mn 2 Sb, because in the phase diagram of Mn-Sb system there are only these two compounds and no solid solution.…”

Distribution of Mn in ferromagnetic (In,Mn)Sb films grown on (001) GaAs using MBE

“…One can note that the triangular hillocks are observed only in the samples with Mn; in the bulk InSb sample, no triangular hillocks are found. The presence of Mn in InSb can result in MnSb clusters [3][4][5][6] and we believe that the triangular hillocks are, in fact, such clusters representing a second magnetic phase in the samples.…”

Possibility of spin-polarized electric current through Mn-, Fe-, Co-, or Ni-doped BaSi2 predicted by their calculated densities of states

“…Examples of ferromagnetic semiconductor materials studied thus far include Mn-doped indium antimonide (InSb) 3) , chromium (Cr)-doped GaN 4) or AlN 5) , and Mn-, iron (Fe)-, cobalt (Co)-, or Cr-doped indium oxide, zinc oxide, titanium oxide, and tin oxide 6)-9) .…”
