چکیده
In monoionic complexes based on Co2+ ions, the second and third harmonics of magnetic susceptibility were found at temperatures 2–4 K, which exceed Néel temperature. The maxima are observed a frequency ~1 Hz, maximum first harmonic is in field 3.2 kOe. An analysis dependences temperature showed that nonlinearity arises as result formation spin glass state slightly higher than this state, there no long-range order, but clusters state. spin-glass compound with ion high anisotropy unusual exchange interaction much smaller single-ion energy.

متن کاملA Crossed Beam and ab Initio Investigation on the Formation of Boronyldiacetylene (HCCCC<sup>11</sup>BO; <italic>X</italic><sup>1</sup><sup>+</sup>) via the Reaction of the Boron Monoxide Radical (<sup>11</sup>BO; <italic>X</italic><sup>2</sup><sup>+</sup>) with Diacetylene (C<sub>4</sub>H<sub>2</sub>; <italic>X</italic><sup>1</sup><sub>g</sub><sup>+</sup>)
The reaction dynamics of the boron monoxide radical (BO; XΣ) with diacetylene (C4H2; XΣg) were investigated at a nominal collision energy of 17.5 kJ mol−1 employing the crossed molecular beam technique and supported by ab initio and statistical (RRKM) calculations. The reaction is governed by indirect (complex forming) scattering dynamics with the boron monoxide radical adding with its boron at...
متن کاملGraphene-on-Diamond Devices with Increased Current-Carrying Capacity: Carbon sp<sup>2</sup>-on-sp<sup>3</sup> Technology
Graphene demonstrated potential for practical applications owing to its excellent electronic and thermal properties. Typical graphene field-effect transistors and interconnects built on conventional SiO2/Si substrates reveal the breakdown current density on the order of 1 μA/ nm (i.e., 10 A/cm), which is ∼100× larger than the fundamental limit for the metals but still smaller than the maximum a...
متن کاملCa<sup>2</sup> signals mediated by bradykinin type 2 receptors in normal pancreatic stellate cells can be inhibited by specific Ca<sup>2</sup> channel blockade
Normal pancreatic stellate cells (PSCs) are regarded as quiescent, only to become activated in chronic pancreatitis and pancreatic cancer. However, we now report that these cells in their normal microenvironment are far from quiescent, but are capable of generating substantial Ca2+ signals. We have compared Ca2+ signalling in PSCs and their better studied neighbouring acinar cells (PACs) and fo...
