Resistive and capacitive switching in capacitor metal/nanocomposite/metal (M/NC/M) structures based on (CoFeB)x(LiNbO3)100-x NC fabricated by ion-beam sputtering with metal content x $\approx$ 8-20 at. % is studied. The peculiarity of the structure synthesis was use increased oxygen ($\approx$ 2*10^-5 Torr) at initial stage growth. films, along nanogranules 3-6 nm size, contained a large number dispersed Co (Fe) atoms (up to ~10^22 cm^-3). Measurements were performed both DC AC (frequency...
We present results of an experimental study structural, magnetotransport, and magnetic properties a disordered system which consists the strained crystalline CoFe nanogranules with size 2--5 nm embedded into B-Al-O oxide matrix large number dispersed Fe or Co atoms. They act in as ions contribute essentially to magnetization at $T$ \ensuremath{\leqslant} 25 K. The conductivity follows $\text{ln}T$ law on metallic side metal-insulator transition wide range metal content variation...
We present a comparative study of the anomalous Hall effect (AHE) and transverse Kerr (TKE) in nonstoichiometric alloys. The data on AHE TKE are consistent with each other clearly indicate intrinsic above room-temperature ferromagnetic order studied samples. argue that this is not produced by phase segregation effects, but rather has global character, while even small level nonstoichiometry alloys drastically changes their magnetic, electrical, optical magneto-optical properties as compared...
A detailed study of the magnetic and transport properties Si${}_{1\ensuremath{-}x}$Mn${}_{x}$ ($x\ensuremath{\approx}0.35$) films is presented. We observe anomalous Hall effect in these up to room temperature. The results measurements data are consistent demonstrate existence long-range ferromagnetic order systems under investigation. correlation samples with their conductivity substrate type shown. theoretical model based on idea a two-phase material, which molecular clusters localized...
The results of a comprehensive study magnetic, magneto-transport and structural properties nonstoichiometric MnxSi1-x (x ≈ 0.51-0.52) films grown by the Pulsed Laser Deposition (PLD) technique onto Al2O3(0001) single crystal substrates at T = 340°C are present. A highlight used PLD method is non-conventional (“shadow”) geometry with Kr as scattering gas during sample growth. It found that exhibit high-temperature (HT) ferromagnetism (FM) Curie temperature TC ∼ 370 K accompanied positive sign...
