    The magnetic moment and magnetization in GaAs/Ga0.84_{0.84}In0.16_{0.16}As/GaAs heterostructures with Mn deluted in GaAs cover layers and with atomically controlled Mn δ\delta-layer thicknesses near GaInAs-quantum well (\sim3 nm) in temperature range T=(1.8-300)K in magnetic field up to 50 kOe have been investigated. The mass magnetization all of the samples of GaAs/Ga0.84_{0.84}In0.16_{0.16}As/GaAs with Mn increases with the increasing of the magnetic field that pointed out on the presence of low-dimensional ferromagnetism in the manganese depletion layer of GaAs based structures. It has been estimated the manganese content threshold at which the ferromagnetic ordering was found.Comment: 8 pages, 3 figure

    Direct SIMS Determination of the InxGa1-xN Mole Fraction

    We demonstrate that our secondary mass ion spectroscopy (SIMS) method for the determination of the mole fraction in solid InxGa1-xN solutions is accurate and reproduceable without need of reference samples. The method is based on measuring relative current values of CsM+ (M=Ga, In) secondary ions. The claim of reliable SIMS determination without reference samples was confirmed by four independent analytical methods on the same samples with a relative error in the InN mole fraction determination below 15

    The magnetic moment and magnetization in GaAs/Ga₀.₈₄In₀.₁₆As/GaAs heterostructures with Mn deluted in GaAs cover layers and with atomically controlled Mn δ-layer thicknesses near GaInAs-quantum well (~3 nm) in temperature range T = 1.8–300 K in magnetic field up to 50 kOe have been investigated. The mass magnetization all of the samples of GaAs/Ga₀.₈₄In₀.₁₆As/GaAs with Mn increases with the increasing of the magnetic field that pointed out on the presence of low-dimensional ferromagnetism in the manganese depletion layer of GaAs based structures.
