Doudin et al - at University of Strasbourg propose that nano ferromagnetic electrodes can create powerful localized force fields which are tuned by an external magnetic field. "Localized field" is a key. Inverse square power laws can make a large difference. Their finding can be understood as similar to a precondition for nanomagnetism in LENR. Of course, this paper is ostensibly not related to LENR, so it would also be a mistake to try to read too much into it. One must first understand the nuances of superparamagnetism, as the gateway to spin-coupling in LENR... then this cross-connection can become apparent. The authors construct nanonickel electrodes in a solution containing paramagnetic molecules and control the electrode's magnetization direction with an external magnetic field. In so doing, they created a conductive molecular-sized switching system which is the chemical equivalent of a spintronics spin valve. Spin coupling is implied. In LENR this molecular level switching would occur at Terahertz blackbody rate of the thermal system, and would act as a pump for extracting spin energy from protons, nickel atoms, or both (as magnons) - which show up as thermal gain in a system where superparamagnetism and superferromagnetism compete with each other. "Magnon" is another key concept for LENR. The high level of spin coupling to magnons is possible as a direct result of competition between superparamagnetic and superferromagnetic particles in motion, and in phase change - as well as a dynamical Casimir effect at the same geometry. Moving from a geometry defined by micron dimensions to nano, when magnetism is involved, brings with it the potential for gains of 1000^2. That, in a nutshell, is what nanomagnetism is all about. Jones And ... for the benefit of the growing "spin-coupling" "nanomagnetism" cadre on vortex, consider inverse cube as it relates to the Biot-Savart Law for magnetism. The parameters for change from square to cube favor the smaller dimensions. The Biot-Savart Law has a cubic power law denominator and ostensibly gives an inverse cube dependence for magnetism in those scenarios. See http://en.wikipedia.org/wiki/Biot%E2%80%93Savart_law
