چکیده
We used the Taylor–Ulitovsky technique to prepare nanocrystalline Co2MnGe Heusler alloy glass-coated microwires with a metallic nucleus diameter of 18 ± 0.1 µm and total 27.2 µm. Magnetic structural studies were carried out determine fundamental magneto-structural characteristics microwires. XRD revealed well-defined structure an average grain size about 63 nm, lattice parameter = 5.62 unique mixture L21 B2 phases. The hysteresis loops measured at different temperatures indicated well-known ferromagnetic behavior for reduced remanent, where monotonic increasing in remanent saturation magnetization occurs. coercivity shows anomalous compared Co2Mn-based curves field cooling heating (FC–FH) demonstrate considerable dependence on applied magnetic field, ranging from 50 Oe 20 kOe. Internal stresses, originated by production process, resulted various phases, which responsible notable difference FC FH versus temperature. Furthermore, expected high Curie temperature, together degree order, make it promising candidate many applications.

Preparation and periodic emission of superlattice CdS/CdS:SnS2 microwires.
Semiconductor superlattice micro-/nanowires could greatly increase the versatility and power of modulating electronic (or excitonic, photonic) transport, optical properties. In this communication, we report growth of a semiconductor CdS/CdS:SnS(2) superlattice microwire through a coevaporation technique with microenvironmental control. Such a novel superlattice microwire can modulate the excito...
