Materials that can be magnetized and attracted to a magnet are called ferromagnetic materials (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Magnetic Smart Materials also have medical applications and it is expected that they will increase in the future. Examples are carrying medications to exact locations within the body and the use as a contrasting agent for MRI scans, assessing the risk of organ damage in hereditary hemochromatosis, determining the dose of iron chelator drugs required for patients with thalassemia, and Now-a-days Scientists are also working on the development of synthetic magnetic particles that can be injected into the human body for the diagnosis and treatment of disease. Spintronics, also known as spin electronics or fluxtronics, is the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices.
