2. Magnetochemistry - Wikipedia

   en.wikipedia.org/wiki/Magnetochemistry

   [2] is a torsion balance which uses a sample in a fixed position and a variable secondary magnet to bring the magnets back to their initial position. It, too, is calibrated against HgCo(NCS) 4 . With a Faraday balance the sample is placed in a magnetic field of constant gradient, and weighed on a torsion balance.

3. Molecule-based magnets - Wikipedia

   en.wikipedia.org/wiki/Molecule-based_magnets

   Molecule-based magnets (MBMs) or molecular magnets are a class of materials capable of displaying ferromagnetism and other more complex magnetic phenomena. This class expands the materials properties typically associated with magnets to include low density, transparency, electrical insulation, and low-temperature fabrication, as well as combine magnetic ordering with other properties such as ...

4. Altermagnetism - Wikipedia

   en.wikipedia.org/wiki/Altermagnetism

   This experiment provided direct evidence of altermagnetic behavior, confirming the existence of this third class of magnetism. [ 17 ] In December 2024, researchers from the University of Nottingham provided the first experimental imaging of altermagnetism, confirming its unique spin-symmetry properties.

5. Gauss (unit) - Wikipedia

   Carl Friedrich Gauß in 1828, aged 50 years old. The gauss (symbol: G, sometimes Gs) is a unit of measurement of magnetic induction, also known as magnetic flux density.The unit is part of the Gaussian system of units, which inherited it from the older centimetre–gram–second electromagnetic units (CGS-EMU) system.

7. Magnetic nanoparticles - Wikipedia

   en.wikipedia.org/wiki/Magnetic_nanoparticles

   Ferrite nanoparticles or iron oxide nanoparticles (iron oxides in crystal structure of maghemite or magnetite) are the most explored magnetic nanoparticles up to date.Once the ferrite particles become smaller than 128 nm [22] they become superparamagnetic which prevents self agglomeration since they exhibit their magnetic behavior only when an external magnetic field is applied.
