  2. Tin - Wikipedia

    en.wikipedia.org/wiki/Tin

    Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO 2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable

  3. Epstein frame - Wikipedia

    en.wikipedia.org/wiki/Epstein_frame

    is the average magnetic path length = 0.94 (constant value) m {\displaystyle m~} is the mass of the sample in kilograms If all conditions are as defined in the standard, the standard deviation of the reproducibility of the values is not greater than 1.5% up to 1.5 T [ clarification needed ] for non-oriented electrical steel and up to 1.7 T for ...

  4. Ferromagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferromagnetism

    Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...

  5. Niobium–tin - Wikipedia

    en.wikipedia.org/wiki/Niobium–tin

    Niobium–tin is an intermetallic compound of niobium (Nb) and tin (Sn), used industrially as a type-II superconductor. This intermetallic compound has a simple structure: A3B . It is more expensive than niobium–titanium (NbTi), but remains superconducting up to a magnetic flux density of 30 teslas [T] (300,000 G), [ 1 ] compared to a limit ...

  6. Magnetic alloy - Wikipedia

    en.wikipedia.org/wiki/Magnetic_alloy

    A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve ): iron (Fe) , nickel (Ni) , or cobalt (Co) .

  7. Kondo effect - Wikipedia

    en.wikipedia.org/wiki/Kondo_effect

    In contrast, as the temperature tends to zero the impurity magnetic moment and one conduction electron moment bind very strongly to form an overall non-magnetic state. The Kondo effect can be considered as an example of asymptotic freedom, i.e. a situation where the coupling becomes non-perturbatively strong at low temperatures and low energies ...

    A man accused of attacking a Colorado reporter after questioning whether he was a citizen and saying “This is Trump’s America now” has had mental health issues for years, his lawyer said.

  9. Titanium nitride - Wikipedia

    en.wikipedia.org/wiki/Titanium_nitride

    Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
