Field-induced static and dynamic yield stresses are explored for magnetorheological (MR) suspensions in an aging, yield stress matrix fluid composed of an aqueous dispersion of Laponite clay. Using a custom-built magnetorheometry fixture, the MR response is studied for magnetic field strengths up to 1 T and magnetic particle concentrations up to 30 v%. The yield stress of the matrix fluid, whic...
effect of static magnetic field (smf) on plants is a matter of debate. in the present study plausible useful effects of smf on wheat plant (triticum aestivum l.) via improvement of antioxidant system and iron/ferritin fortification were evaluated. the plants were cultivated in pots and in their reproductive stages were treated with or without a 30 mt smf for 4 days, each 5h. the activity of ant...
Abstract This article describes the analysis of NMR (Nuclear Magnetic Resonance) stabilizer signal. field standard is created using an electromagnet. Sufficiently high stability magnetic achieved with help a probe. The phenomenon makes possible very accurate measurements static field, but resulting depends also on supporting electronics. An has been done and tolerances measured quantities have ...
We present a neutron-scattering study of the static and dynamic spin correlations in the underdoped high-temperature superconductor YBa2Cu3O6.45 in magnetic fields up to 15 T. The field strongly enhances static incommensurate magnetic order at low temperatures and induces a spectral-weight shift in the magnetic-excitation spectrum. A reconstruction of the Fermi surface driven by the field-enhan...
