Recent advances in technology involving magnetic materials require development of novel advanced magnetic materials with improved magnetic and magneto-transport properties and with reduced dimensionality. Therefore magnetic materials with outstanding magnetic characteristics and reduced dimensionality have recently gained much attention. Among these(More)
We studied the effect of magnetoelastic anisotropy on domain wall (DW) dynamics and remagnetization process of magnetically bistable Fe-Co-rich microwires with metallic nucleus diameters (from 1.4 to 22 μm). We manipulated the magnetoelastic anisotropy applying the tensile stresses and changing the magnetostriction constant and strength of the internal(More)
The giant magneto-impedance (GMI) effect has been studied in 3 different families of amorphous wires: conventional amorphous wires (125 μm in diameter), cold drawn wires (50 and 20 μm in diameter) and thin glass coated amorphous microwires (with metallic nucleus diameter of about 15 μm). These wires have been investigated in the frequency range 1 – 500 MHz.(More)
The effect of the external magnetic field on microwave response from composites containing CoFeSiBCr amorphous wires has been demonstrated by measuring S-parameters in free space in the frequency band of 0.9-17 GHz. Two types of composites made of lattices of continuous and short -cut wires are considered to employ different types of spectra of the(More)
We present a concept and prototype of a memory element based on current driven magneto-impedance (MI) effect that stores the binary data (0, 1) as the orientation of the magnetization. The magnetization orientation in the surface layer with tilted anisotropy easy axis can be switched controllably between two stable states by applying current pulses of the(More)
Beam test results for MSGC's with thick metal strips. Abstract Micro Strip Gas Counters with robust gold strips have been developed at IMEC, the Interuniversity Microelectronics Center at Leuven, in Belgium. The electroless plating technology was used, allowing to achieve a strip thickness of up to 1.6 m on 10x10 cm 2 substrates. Results on signal to noise(More)
The heating properties of Fe71.7Si11B13.4Nb3Ni0.9 amorphous glass-coated microwires are explored for prospective applications in magnetic hyperthermia. We show that a single 5 mm long wire is able to produce a sufficient amount of heat, with the specific loss power (SLP) reaching a value as high as 521 W/g for an AC field of 700 Oe and a frequency of 310(More)
We report on studies of domain wall propagation of magnetically-bistable Fe-Co-rich microwires paying attention on the effect of applied and internal stresses. We measured magnetic domain propagation in various magnetic Fe-Co-rich amorphous microwires with metallic nucleus diameters (from 2.8 microm to 18 microm) using Sixtus Tonks-like experiments. We(More)
A possibility of abiogenic synthesis of natural nucleotides in solid state under the influence of UV and gamma radiation has been shown for a mixture of nucleosides and dihydrophosphate. Adenosine and deoxyadenosine were used as initial substances. During adenosine and deoxyadenosine phosphorylation under the action of UV radiation (lambda = 254 nm), only(More)
