Does iron oxide have magnetic properties?
Like iron, iron oxide has magnetic properties. Because the unpaired electrons make a material magnetic, iron oxide is less magnetic than iron. Iron oxide is therefore called a paramagnetic material.
What is the magnetic properties of iron?
Most people think of iron as a magnetic material. Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C.
Is Fe2O3 magnetic?
Iron (III) oxide has four polymorphs: α-Fe2O3 (hematite), β-Fe2O3, γ-Fe2O3 (maghemite) and ε-Fe2O3. They are all ferrimagnetic, which means they all attract to magnets, except for α-Fe2O3 (hematite) which is anti-ferromagnetic.
What are the properties of iron oxide?

What is magnetic oxide?
n. (Elements & Compounds) a red crystalline insoluble oxide of iron that occurs as haematite and rust and is made by heating ferrous sulphate: used as a pigment and metal polish (jeweller’s rouge), and as a sensitive coating on magnetic tape. Formula: Fe2O3. Systematic name: iron (III) oxide.
Is Fe2O3 paramagnetic or diamagnetic?
Gamma and epsilon type Fe2O3 are ferromagnetic; alpha Fe2O3 is a canted antiferromagnetic while beta type Fe2O3 is a paramagnetic material.
Is iron magnetic?
Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic. Two metals that aren’t magnetic are gold and silver.
What is iron oxide particles?
Iron oxides are common natural compounds and can also easily be synthesized in the laboratory. Iron oxide (IO) nanoparticles consist of maghemite (γ-Fe2O3) and/or magnetite (Fe3O4) particles with diameters ranging from 1 and 100 nanometer and find applications in magnetic data storage, biosensing, drug-delivery etc.
