  2. Ferromagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferromagnetism

    Ferromagnetism is an unusual property that occurs in only a few substances. The common ones are the transition metals iron, nickel, and cobalt, as well as their alloys and alloys of rare-earth metals. It is a property not just of the chemical make-up of a material, but of its crystalline structure and microstructure.

  3. Transition metal - Wikipedia

    en.wikipedia.org/wiki/Transition_metal

    A characteristic of transition metals is that they exhibit two ... Metallic iron and the alloy alnico are examples of ferromagnetic materials involving transition ...

  4. Curie temperature - Wikipedia

    en.wikipedia.org/wiki/Curie_temperature

    Metals. Above the Curie temperature, the atoms are excited, and the spin orientations become randomized [ 9 ] but can be realigned by an applied field, i.e., the material becomes paramagnetic. Below the Curie temperature, the intrinsic structure has undergone a phase transition , [ 16 ] the atoms are ordered, and the material is ferromagnetic ...

  5. Ferrimagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferrimagnetism

    This compensation point is observed easily in garnets and rare-earth–transition-metal alloys (RE-TM). Furthermore, ferrimagnets may also have an angular momentum compensation point, at which the net angular momentum vanishes. This compensation point is crucial for achieving fast magnetization reversal in magnetic-memory devices.

  6. Nickel - Wikipedia

    en.wikipedia.org/wiki/Nickel

    Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium. Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature.

  7. Kagome metal - Wikipedia

    en.wikipedia.org/wiki/Kagome_metal

    In solid-state physics, the kagome metal or kagome magnet is a type of ferromagnetic quantum material. The atomic lattice in a kagome magnet has layered overlapping triangles and large hexagonal voids, akin to the kagome pattern in traditional Japanese basket-weaving .

  8. Platinum group - Wikipedia

    en.wikipedia.org/wiki/Platinum_group

    The three elements above the platinum group in the periodic table (iron, nickel and cobalt) are all ferromagnetic; these, together with the lanthanide element gadolinium (at temperatures below 20 °C), [4] are the only known transition metals that display ferromagnetism near room temperature.

  9. Ferroics - Wikipedia

    en.wikipedia.org/wiki/Ferroics

    The basis of ferroics is to understand the large changes in physical characteristics that occur over a very narrow temperature range. The changes in physical characteristics occur when phase transitions take place around some critical temperature value, normally denoted by . Above this critical temperature, the crystal is in a nonferroic state ...
