Abstract: PURPOSE: An MTJ(Magnetic Tunnel Junction) device is provided to leave freedom to tune the coercive field and to obtain an appreciable MR(Magnetic Resistance) by using a ferromagnetic layer and an anti-parallel layer. CONSTITUTION: In the device, a block(100) of exemplary ferromagnetic material comprising iron (Fe) atoms(120) and terbium (Tb) atoms(140). It is generally understood that the ferromagnetic class of materials generally consists of two sublattices, usually a rare earth metal such as terbium and a transition metal such as iron. At low temperatures, i.e. below compensation temperature, the rare-earth moment(140a) shown by the long arrows is larger than that of the transition metal moment(120a) shown by the short arrows. Thus, there is a net magnetization in the direction of the rare earth moment. However, as temperature rises, the rare-earth moment decreases more rapidly because it is subjected to weaker exchange forces. There is an intermediate temperature, sometimes called as compensation temperature (Tcomp), at which the two lattices cancel each other out, and net magnetization of the ferromagnetic material drops to zero.
