【 摘 要 】

We have studied the magnetic properties of nonsuperconducting RuSr2L1.5Ce0.5Cu2O10 [L=Y, Dy, and Ho (Ru-1222)] compounds synthesized under high pressure (6 Gpa) at elevated temperature. These materials become magnetically ordered at T-M=152(2) K regardless of L. The wide ferromagneticlike hysteresis loops, which open at 5 K, close themselves around T-irr=90-100 K and the remanent magnetizations (M-rem) and coercive fields (H-C) become zero. Surprisingly, at T-irr
