MAGNETIC ANISOTROPY OF ROCKS. “it became apparent that both ferromagnetism and paramagnetism contribute to the total magnetic anisotropy.” https://lnkd.in/edVSe9a View in LinkedIn

"MAGNETIC ANISOTROPY is the directional dependence of a material's magnetic properties. The magnetic moment of magnetically anisotropic materials will tend to align with an 'easy axis' which is an energetically favorable direction of spontaneous magnetization." https://lnkd.in/eRB63F2 View in LinkedIn

MAGNETIC ANISOTROPY IN RETINAL RODS in the eye is due to the orientation of molecules in the rod disk membranes. https://lnkd.in/eyTyisn View in LinkedIn

MAJOR BIOMAGNETS. "Magnetic anisotropy in biological materials has been increasingly reported. The orientation of retinal rod outer segments, chloroplasts, photosynthetic algae and bacteria, purple membranes, and nucleic acids in magnetic fields of several kilogauss have been attributed to diamagnetic anisotropy of the molecular components." https://lnkd.in/eadsVkd View in LinkedIn

FERROMAGNETS. "Some crystalline states are capable of ferromagnetic behavior because of quantum mechanic considerations. Electrons in neighboring orbitals in certain crystals "know" about each other's spin states. In order to avoid sharing the same orbital with the same spin (not allowed by Pauli' exclusion principle) electron spins in such crystals act in a coordinated fashion." https://lnkd.in/eaPaaK2 View in LinkedIn

EARLY INSIGHT. "Relations may exist between ferroelectricity, the formation of liquid crystals, and the generation of electric impulses in nerves and muscles." https://lnkd.in/eBe5QYb View in LinkedIn

THE ASYMMETRIC UNIVERSE. "Ferroelectricity is an example of the general phenomenon in which a system can be switched between two states of orientation by the application of a force. These phenomena are essential for many organic, biological molecules, and all living systems in our asymmetric universe." https://lnkd.in/eBe5QYb View in LinkedIn

PIEZO-AMINO ACIDS. "Piezoelectricity is a phenomenon which can exist only in noncentrosymmetric materials. The main building blocks of life are proteins, and the majority of protein crystals and noncentrosymmetric. Proteins are made of combinations of the 20 known amino acids, the majority of which also have noncentrosymmetric crystal structures...as a consequence, these amino acids poses piezoelectric properties." https://lnkd.in/eBe5QYb View in LinkedIn

"BIOPIEZOELECTRICITY is exhibited in large-scale biological systems such as proteins, biopolymers, polysaccharides, organelles and glands." https://lnkd.in/eBe5QYb View in LinkedIn
