Title: ON THE POSSIBILITY OF FERROMAGNETISM AND HALF-METALLICITY IN LOCAL
MOMENT
SYSTEMS
Abstract: We use the Kondo lattice model to investigate the possibility of
ferromagnetism and half-metallicity in local moment systems. Using the
spectral density approach and making use of the
fact that the spontaneous magnetization of local moment and the itinerant
electron polarization are coupled, we derive an expression for the
paramagnetic susceptibility. The magnetic ordering
temperature is determined from the singularities of the susceptibility. The
magnetic phase diagram is constructed in T −n(band filling) plane. It
is found that ferromagnetism is possible
only for small values of n. It is also found that the temperature drives the
transition of the system from half-metal to metal. | N***m
