Ferromagnetism
(NORASHIDA MOHD RAZALI,4SSCZ)
-
Material Usage
:basketball:common = Co,Ni,Fe + lodestone(natural magnetized material) & rare earth metal compound
:basketball:magnetic storage in form of data:
-->cheaper form to store data
-->able to re-use (Hysteresis)
:basketball:ferro magnetized,lose ability to lose M =not able back to original state without M
:basketball:opposite magnetic field applied -->creation of hysteresis loop.
:basketball:unique effect allowing material to retain data, after magnetizing field drop to 0

Temperature Dependence
:shark:below Tc--> spin ferro with same magnitude,well-ordered, M is ferromagnetic with aligned moments
