27Al-NMR Investigations on PrAl2 and PrxLa1−XAl3, x=1.0, 0.5, 0.25
Intermetallic compounds of rare earths exhibit an interesting magnetic behavior because of the large conduction electron spin polarization described by RKKY theory and its influence on properties measured by nuclear magnetic resonance1–4. Moreover, substances with singlet crystal field ground states and f-f exchange energies below a critical value (Van Vleck paramagnetic compounds) are considered for nuclear cooling.
