Magnetic-Moment Reduction in the Anderson Lattice System, CeAl2: Pressure Effects

Measurements of the initial magnetic susceptibility of CeAl2 have been made at a hydrostatic pressure of 8 kbar and compared with the ambient pressure behavior. Finite pressure has the effect of both reducing the magnetic moment and lowering the Neel temp. Both effects are understood within a simple...

Zusammenfassung:Measurements of the initial magnetic susceptibility of CeAl2 have been made at a hydrostatic pressure of 8 kbar and compared with the ambient pressure behavior. Finite pressure has the effect of both reducing the magnetic moment and lowering the Neel temp. Both effects are understood within a simple moment-reduction model which borrows from the single-impurity Kondo problem.18 refs.--AA
