The structural, magnetic, and electronic properties of dilute Mn-doped scandium nitride thin films grown by radio frequency N-plasma molecular beam epitaxy are explored. The results indicate a small magnetization extending up to as high as 350K. There is a slight dependence on the manganese concentration, with the lower Mn concentration showing a larger saturation magnetization.

Reported here is a face-capped Fe(ii) molecular tetrahedron, [Fe(4)L(4)](BF(4))(8), . Single crystal X-ray diffraction at 153 and 293 K suggest spin crossover (SCO) and variable temperature magnetic susceptibility measurements confirm displays thermally driven SCO behaviour in the solid state and in dilute acetone solution centred around 284-288 K.

Confinement of electrically charged test particles in the dilute plasma of mo-nopoles and pointlike magnetic dipoles is studied. We calculate the tension of the string emerging between the infinitely separated test particles. The string tension is an increasing function of the dipole density provided other parameters of the plasma are fixed. The relevance of our results to confining gauge theor...

We study dilute suspensions of magnetic nanoparticles in a nematic host, on two-dimensional polygons. These systems are described by order parameter and spontaneous magnetization, the absence any external fields. stable states terms critical points an appropriately defined free energy, with nemato-magnetic coupling energy. numerically interplay between shape regular polygon, size strength for m...

Some universal amplitude ratios appropriate to the φ2,1 perturbation of the c = 7 10 minimal field theory, the subleading magnetic perturbation of the tricritical Ising model, are explicitly demonstrated in the dilute A3 model, in regime 1. AMS classification scheme numbers: 82B23, 81T40
