In TFB technique, the thin film radius is typically of the order of 100 pm, far larger than the contact film radius likely to be formed when two micron-sized droplets approach. The magnetic chaining technique overcomes this limitation, allowing the direct measurement of force-distance profiles between liquid colloidal droplets. This technique exploits the properties of monodisperse ferrofluid... 

We provide a symmetry analysis and a calculation of the frequency-field dependencies of the different 3D AFM states for the underdoped Cu xMxGe02. Our consideration based on the supposition about existence or absence of structural distortions, which result into an alternation of the AFM exchange along magnetic chains. Two types of wave vectors...

The interchain dipolar term may be particularly important in the case of two magnetic chain compounds. The pO term is diffusive,... 

TTF-TCNQ is a two-conducting (both magnetic) chain compound. In Fig. 2 the total susceptibility is shown. Decomposition into the two components required a study of the g factor weighted by the susceptibilities of the two chains [28] or NMR experiments on isotopically enriched molecules [29]. 

Due to the nature of the magnetic ions involved, both having a 6At fundamental term, the magnetic chains of Ba7MnFe6F34 are likely to be well described by an isotropic classical spin model, similar in principle to the one developed by Fisher [7] for the simple chain. This later uses however the recurrence relation (written here with trivial notations) ... 

The uniform Heisenberg magnetic chain has been an object of study for three quarters of a century, dating back to the initial work of Bethe. Unhke the equivalent Ising and XY-chains, the Heisenberg model cannot be solved analytically. The first calculations of the susceptibihty and specific heat...

The materials studied are insulating uni- or bimetallic magnetic chains and pure or intercalated MPS3 layers.
