Title: The structural and magnetic phase transitions in Ca_0.73La_0.27FeAs₂ with electron overdoped FeAs layers.

Abstract

Here we report a study of the Ca_0.73La_0.27FeAs₂ single crystals. We unravel a monoclinic to triclinic phase transition at 58 K, and a paramagnetic to stripe antiferromagnetic (AFM) phase transition at 54 K, below which spins order 45° away from the stripe direction. Furthermore, we demonstrate this material is substantially structurally untwinned at ambient pressure with the formation of spin rotation walls (S-walls). Finally, in addition to the central-hole and corner-electron Fermi pockets usually appearing in FPS, angle-resolved photoemission (ARPES) measurements resolve a Fermiology where an extra electron pocket of mainly As chain character exists at the Brillouin zone edge.

Magnetic properties and magnetostriction of twin-free single-crystal Tb{sub 0.27}Dy{sub 0.73}(Fe{sub 1{minus}{ital x}}Al{sub {ital x}}){sub 2}

Journal Article Wang, J ; Wu, G ; Zhao, X ; ... - Journal of Applied Physics

Magnetization curves, Curie temperature, and lattice constants of twin-free [111]-oriented single-crystal Tb{sub 0.27}Dy{sub 0.73}(Fe{sub 1{minus}{ital x}}Al{sub {ital x}}){sub 2} ({ital x}=0, 0.1) were investigated. It was observed that with the substitution of Al for Fe, Curie temperature and magnetocrystalline anisotropy decrease, and lattice constants increase. It is shown from the curves of magnetic moment versus temperature that the anisotropy compensation temperature of Tb{sub 0.27}Dy{sub 0.73}(Fe{sub 0.9}Al{sub 0.1}){sub 2} is 280 K, which is higher than 260 K of Tb{sub 0.27}Dy{sub 0.73}Fe{sub 2}.

Journal Article Armstrong, W D - Journal of Applied Physics

The present analysis provides Tb{sub (0.27{minus}0.30)}Dy{sub (0.73{minus}0.70)}Fe{sub (1.9{minus}2.0)} magnetization and magnetostriction states during applied magnetic field and stress processes by minimizing the total magnetic free energy in the presence of a parameter selected inverse exponential magnetic free energy distribution. A comparison between experimental and model results shows that the model provides a qualitatively accurate description of the magnetostriction and magnetization in Tb{sub (0.27{minus}0.30)}Dy{sub (0.73{minus}0.70)}Fe{sub (1.9{minus}2.0)} during applied magnetic field processes for a range of constant uniaxial applied stresses. Therefore, the model appears to be a useful tool for the analysis of Tb{sub (0.27{minus}0.30)}Dy{sub (0.73{minus}0.70)}Fe{sub (1.9{minus}2.0)} applications with constant stress ormore »« less

Critical film thickness dependence on As flux in In{sub 0.27}Ga{sub 0.73}As/GaAs(001) films

Journal Article Riposan, A ; Mirecki Millunchick, J ; Pearson, Chris ; ... - Applied Physics Letters

The transition between planar and nonplanar growth is examined for compressively strained In{sub 0.27}Ga{sub 0.73}As/GaAs(001) films using reflection high energy electron diffraction, atomic force microscopy, and scanning tunneling microscopy (STM). For a narrow range of temperature and composition, the critical thickness (t{sub SK}) is strongly dependent on As flux. For high values of As flux, t{sub SK} increases by more than a factor of 2. The morphology of three-dimensional islands formed during the initial stages of nonplanar growth is also characterized by high resolution STM.

Capacitance-voltage characteristics of the p-Cd{sub 0.27}Hg{sub 0.73}Te-based structures with a wide-gap graded-gap surface layer

Journal Article Vasil'ev, V V ; Mashukov, Yu P - Semiconductors

Capacitance-voltage characteristics of the structure In-SiO{sub 2}-(graded-gap layer Cd{sub 0.71-0.27}Hg{sub 0.29-0.73}Te)-p-Cd{sub 0.27}Hg{sub 0.73}Te-GaAs are investigated at temperatures of 80 K and higher. The characteristics have the hysteresis, specifically, the characteristic is similar to a forward portion of the usual high-frequency characteristic (from enrichment to inversion), while the reverse portion has an extended plateau, in which the capacitance of the space-charge region is larger by a factor of approximately 2. To interpret the capacitance-voltage characteristic, the effect of partial screening of the graded-gap part of the space-charge region from the electric field of the test signal, as well as the effectmore »« less
