Magnetocrystalline anisotropy is found in many magnetic materials which means that the energy of a magnet depends on the magnetization direction. This keeps our windshield wipers moving and our toy magnets attached to the fridge. However, on changing the direction of the field that aligns the magnetic moments, the aligned magnetization normally remains nearly unchanged.
Anisotropic magnetoresistance (AMR) is the difference in the resistivity of ferromagnetic materials in external magnetic field when the field is applied along or perpendicular to the current.
Vinayak P. Dravid, Northwestern University IRG1, Synergistic Linear and Nonlinear Phenomena in Multifunctional Oxide Ceramic Systems The reduced size of materials with controlled internal structure (i.e., grain size, crystal orientation, etc.) leads to novel, unexpected phenomena and a very broad spectrum of technologically significant properties.
