Assembly Method for Three-Dimensional MEMS Saves Chip Space
... MEMS assembly with one flap that has a spring beam (an offset slab). This spring beam increases the magnetic field strength needed to raise the flap and also causes the flaps to operate asynchronously in an increasing magnetic field. The spring beam also provides variable resistance to the flap when ...

... the speed of light c are absorbed into the physical variables. As a result, they simply can be substituted by unity. Of course, this doesn’t mean that π = 1/4 at all! The advantage of this “none” unit system in FLASH is to provide a very simplified set of Maxwell’s equations in their final form. Thr ...

Magnetochemistry
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic. The magnitude of the paramagnetism is expressed as an effective magnetic moment, μeff. For first-row transition metals the magnitude of μeff is, to a first approximation, a simple function of the number of unpaired electrons, the spin-only formula. In general, spin-orbit coupling causes μeff to deviate from the spin-only formula. For the heavier transition metals, lanthanides and actinides, spin-orbit coupling cannot be ignored. Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.
