There has been substantial research showing the effects of Extremely Low Frequency Electromagnetic Fields (ELF-EMF) on various properties of liquids, among the most notable being the acidity of a solution. ELF-EMFs have amplitudes typically measured on the scale of microteslas, and have frequencies comparable to the cyclotron frequency of the molecule its ionic form. It is hypothesized that the magnetic field changes the coordination of water, which in turn affects the pH of the solution. This is difficult to measure directly, but it can be measured by adding a molecule that can be detected by IR spectroscopy that is sensitive …

Manipulation of magnetically ordered states by electrical means is a promising approach towards novel spintronics devices. We report on the electric control of surface magnetism in Cr2O3 thin films and uniaxial anisotropy in ferroelectric/ferromagnetic heterostructures, respectively. Artificial magnetoelectricity is realized in a BaTiO3/Fe heterostructure. Here, thermally induced coercivity changes of the Fe hysteresis loop are used to derive the stress imposed by the ferroelectric BaTiO3 substrate on the adjacent Fe film. Electrically induced coercivity changes give rise to a giant magnetoelectric susceptibility in the vicinity of the magnetic coercive field.
