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: 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 protein in the body that contains iron and helps store it, mainly found in the liver, spleen, and intestines.

Example: Ferritin levels can indicate how much iron is stored in the body.

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: 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.

Definition: Describing a type of rock or mineral that has iron and magnesium as its main elements.

Example: Basalt is a common example of a ferromagnesian rock.

Definition: A material that can be magnetized and retains its magnetic properties even after the external magnetic field is removed, similar to iron.

Example: Iron is a common example of a ferromagnet used in many applications.

Definition: Relating to materials like iron, nickel, or cobalt that can be magnetized and retain their magnetism even after the external magnetic field is removed.

Example: Iron is a ferromagnetic material, which means it can be magnetized easily.

Definition: The process in which some materials can become permanent magnets when they are exposed to a magnetic field.

Example: Iron exhibits ferromagnetism, allowing it to become a magnet when near a magnetic field.

Definition: Relating to or containing iron, especially in a specific form or state.

Example: The ferrous materials are often used in construction due to their strength.
