From extensive P-31 NMR and As-75 NQR studies on Yb-4(As1-xPx)(3), both ons
et of microscopic anomaly in the magnetic properties below about 7 K and de
coupling between the magnetic and transport properties also from the viewpo
int of low-energy spin dynamics are concluded. (C) 2000 Elsevier Science B.
