W. Wagener et al., MAGNETIC ORDER IN LA1.85-XNDXSR0.15CUO4 WITH LESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-0.60, Physical review. B, Condensed matter, 55(22), 1997, pp. 14761-14764
Spontaneous muon spin rotation is observed in muon spin relaxation exp
eriments on La1.8-xNdxSr0.15CuO4 with 0.30 less than or equal to x les
s than or equal to 0.60, proving the onset of magnetic order below 30
K. The rotation frequencies and the damping rate will be compared to t
hose of La2CuO4 and La1.7Nd0.3CuO4. Below approximate to 4 K, there is
an increase of the coupling between the moments of Nd and Cu, which c
an be observed in the muon-rotation frequency and the damping rate.
