Definition: A type of protein that contains iron and is found in green plants and some bacteria, helping to carry electrons during important chemical reactions like photosynthesis.

Example: Ferredoxin plays a crucial role in the process of photosynthesis by transferring electrons.

Definition: Describing something that contains or looks like iron.

Example: The ferreous material was used in the construction of the bridge.

Definition: Relating to or containing iron, especially in a form with a higher valence than ferrous compounds.

Example: The ferric oxide was used in the chemical reaction.

Definition: A type of material that has magnetic properties, where the magnetic moments of atoms or ions are aligned in opposite directions but do not completely cancel each other out, resulting in a net magnetic moment.

Example: Ferrimagnets are used in various electronic devices due to their unique magnetic properties.

Definition: Describing a material that has two types of magnetic ions that align in opposite directions, resulting in a net magnetic effect.

Example: Ferrimagnetic materials are often used in magnetic storage devices.

Definition: A type of magnetism where materials have unequal magnetic moments that do not completely cancel each other out, resulting in some overall magnetization even at low temperatures.

Example: Ferrimagnetism is observed in certain materials like magnetite, where the magnetic moments of the atoms are unequal.

Definition: A type of nonmetallic compound that is usually magnetic and made from iron oxide combined with other oxides. It is used in electronic devices and has high electrical resistivity.

Example: Ferrite materials are commonly used in the production of transformers and inductors.

Definition: A type of chemical compound made of iron sandwiched between two cyclopentadienyl rings, known for its stability and use in various chemical applications.

Example: Ferrocene is often used in research for its unique properties as a metallocene.

Definition: A type of salt that contains a specific anion made of iron and cyanide, often used in creating blue pigments and other chemical applications.

Example: Ferrocyanide is commonly used in the production of Prussian blue pigment.

Definition: Relating to materials that can maintain an electric charge even after the electric field is removed, often used in electronics and technology.

Example: The researchers developed a new ferroelectric material for better energy storage devices.

Definition: A material that exhibits spontaneous electric polarization, which can be reversed by an external electric field.

Example: The researchers studied the properties of a ferroelectric to improve electronic devices.
