In the current study, we have succeeded to fabricate Co2FeSi Heusler alloy glass-covered microwires with magnetic core nucleus diameter d = 4.36 µm and total D 17.55 µm, high Curie temperature (Tc>1100 K) well-defined anisotropy for spintronic devices application. The properties of as-prepared annealed at different (873 K, 973 K 1073 1 h) been investigated. Strong dependence on annealing condit...

Abstract Glass samples with the composition 40 Bi 2 O 3 -60 GeO -x Er are prepared using melt quenching procedure. Fourier-transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), Ultraviolet/Visible/Near-infrared (UV/Vis–NIR) absorption, photoluminescence (PL), and X-ray diffraction (XRD) used to characterize glass glass–ceramic materials. The transition crystallization tem...

Magnetization measurements with the magnetic field parallel to the c-axis were performed on overdoped Bi2¡ xPbxSr2CaCu2O8+ ± single crystals. Different from undoped Bi2Sr2CaCu2O8+ ± single crystal, a pronounced anomalous peak with maximum peak field over 5000 G can be observed in enlarging temperature window from 0.2Tc to 0.9Tc; both the anomalous magnetization peak H2p and the sharp onset of t...

The thermodynamic response functions of water display anomalous behaviors. We study these anomalous behaviors in bulk and confined water. We use nuclear magnetic resonance (NMR) to examine the configurational specific heat and the transport parameters in both the thermal stable and the metastable supercooled phases. The data we obtain suggest that there is a behavior common to both phases: that...

In active microrheology, a strong external force is applied to a colloidal probe immersed in a complex fluid, so that among other quantities the nonlinear force-velocity relation can be measured. It provides information on the local viscoelastic properties of the complex fluid or soft solid. Generally, in dense fluids, the probe’s friction coefficient decreases strongly with increasing force [1...

A model-free theoretical framework for a phenomenological description of spinlattice relaxation by anomalous translational diffusion in inhomogeneous systems based on the fractional diffusion equation is developed. The dependence of the spinlattice relaxation time on the size of the pores in porous glass Vycor is experimentally obtained and found to agree well with our theoretical predictions. ...
