Another spin

The Proton - Spin Crisis : another ABJ anomaly ?

Using one spin-transition to trigger another in solid solutions of two different spin-crossover complexes.

Phase-pure solid solutions of [Co(terpy)(2)][BF(4)](2) and [M(bpp)(2)][BF(4)](2) (M = Fe or Ru, bpp = 2,6-dipyrazol-1-ylpyridine) have been prepared. The spin-state of the [Co(terpy)(2)](2+) dopant is modulated by the spin-state of the [Fe(bpp)(2)](2+) centres in the iron-containing materials.

Parody: Another Revision

The vast diversity of the proposed definitions of parody, both before and after the twentieth century, can be an emblem of the lack of a thorough agreement amongst the literary critics about the definition of this literary technique (genre?!). While there is not a comprehensive all-accepted definition of parody, modern and postmodern literatures both exhibit a wide application of it. After look...

Yet Another Way to Obtain Low Temperature Expansions for Discrete Spin Systems

I present a modification of the shadow-lattice technique, which allows one to derive low temperature series for discrete spin models to high orders. Results are given for the 3-d Ising model up to 64 excited bonds, for the 4-d Ising model up to 96 excited bonds and the 3-d Potts model up to 56 excited bonds. 1 Series expansions are a major tool to obtain critical properties of statistical syste...
