  • Spin-dependent tunneling occurs because spin-up and spin-down electrons occupy different densities of states in a ferromagnet.

I mean that the spontaneous magnetization of a ferromagnet would be lower than saturation.

Examples

  • Gadolinium's magnetocaloric effect is from two and a half to three times larger than the familiar ferromagnet iron, which orders well above room temperature.

    Academic text (1994)
  • When these spin-down charges tunnel across the insulating barrier, they are accepted into the numerous empty spin-down states on the other side, provided that the two ferromagnets have the same orientation.

  • I mean that the spontaneous magnetization of a ferromagnet would be lower than saturation.

  • Simple examples are the domains in a ferromagnet; domain walls separate regions where magnetic dipoles are aligned.

    Academic text (2005)
  • The technique works because the heat transfer fluid—helium gas that passes through a bed of ferromagnet particles—is distinct from the solid refrigerant.

    Academic text (1994)
  • Because the question was central to particle physics (in particular, quantum chromodynamics) and condensed matter physics (low-dimensional ferromagnets), Adrian considered a mathematically rigorous resolution to be of great importance.

    Academic text (2002)
  • A ferromagnet, like iron, can become magnetized and will remain that way even without a magnetic field.

  • Many consumer products, such as refrigerator magnets, are made from ferromagnet materials.

  • When the ferromagnet is heated above its Curie temperature, it loses its magnetic properties.

Morphology

ferromagnet = magnet (semi-transparent) = ferro + magnet

The combining form 'ferro-' means 'iron' but is a technical/combining form rather than a standalone English word, so the relation to 'magnet' is clear to science-literate learners but not obvious to an average B1 learner.

Etymology

Ferromagnet combines ferro- ('iron') and magnet ('magnet'), so the word literally means an 'iron magnet'. That's why a ferromagnet is a material, like iron, that easily becomes magnetic and can keep its magnetism.
