A novel approach for measuring the growth rate during GaN deposition under nitrogen-limited conditions (i.e., gallium-rich conditions) is presented. The method based on analysis of variations in optical signal measured by a pyrometer two-step process, initial Ga-rich regime and subsequent through consumption excess Ga nitrogen flux. This provides precise accurate way to determine as function plasma generation parameters, such gas flux RF power.
In this paper, we present a detailed study of the oscillating magnetic relaxation in synthetic antiferromagnet (SAF) with two ferromagnetic Co layers different thicknesses separated by an Ir spacer. The four stable states SAF are determined mutual alignment moments and controlled both interlayer exchange interaction Zeeman energy. specific variations and/or temperature allow existence ``triple point,'' which corresponds to coincidence critical switching fields for or three interstate...
The magnetic field effect on the surface oxidation of Czochralski-grown Si single crystals has been observed via atomic force microscopy, electron secondary emission ion and Auger spectroscopy, x-ray photoelectron spectroscopy. changes in concentration oxygen complexes chemical elements crystal exposed to a 0.17 T are evidence spin dependent reactions involving unstable intermediate Si–O–Si as precursors. experimental data have discussed terms theory controlled by field.
Two synthetic antiferromagnet bilayer systems with strong perpendicular anisotropy CoFeB/Ta/CoFeB and Pt/Co/Ir/Co/Pt have been grown using sputtering techniques. For both two types of magnetization transitions studied. The first one concerns from a state where magnetizations the magnetic layers are parallel (P state) to aligned antiparallel (AP state). second between possible alignments (AP+ AP-). after-effect measurements can be understood in frame nucleation-propagation model. Time...
The evolution of the switching field between stable states in MgO/CoFeB/Ta/CoFeB/MgO/GaAs and Pt/Co/Ir/Co/Pt/Ta/SiO2 synthetic ferrimagnets with perpendicular anisotropy as a function magnetic sweeping rate (MFSR) 0.1–104 Oe/s has been studied. most significant effect MFSR is an inversion interstate transition sequence. In heterostructure, increase switches dominant mechanism magnetization reversal from propagation domain walls to nucleation reversed areas. Pt/Co/Ir/Co/Pt/Ta/SiO2, affects...
Thick SmCo films of 500 nm thickness were deposited by RF sputtering in W/SmCo/W structures on Si substrate. After annealing at 650 - 750ºC, the as grown soft amorphous structure transforms into a mixture crystalline Sm2Co17 and SmCo5 hard magnetic phases. Annealing 650°C leads to film crystallization with an average grain size 64 nm, coercivity 0.5 T remanence magnetization about for maximum applied field 2 T. The decreases 20% upon 750°C, while increase up 73 1.1 T, respectively. Series...
Dynamics of magnetization relaxation the MnSb clusters under applied magnetic field has been studied in 8–300 K temperature range. The lognormal distribution ferromagnetic cluster sizes f(D) extracted from and dependences viscosity S(T, H) GaMnSb thin films. An average diameter D = 55 nm is agreement with force microscopy data.

We measured the conductance of bilayer lipid membranes diphytanoylphosphatidylcholine induced by interaction with cubic magnetic nanoparticles (MNPs) cobalt ferrite 12 and 27 nm in size coated a hydrophilic shell. The MNP coating is human serum albumin (HSA) or polyethylene glycol (PEG). added to bulk solution causes formation metastable conductive pores, which, turn, increases integral membranes. increase increasing concentration was practically independent particle size. dependence on...
