| 摘 要： | A new low_temperature anomalous magnetism at about 29 K for the oxygen doped (Eu 1- x Y x ) 2CuO 4 and Sm 2CuO 4, prepared under high pressure, has been investigated. This anomaly originated from different mechanisms to weak ferromagnetism (WF) behavior of T′ phase, and should be assigned to the ferromagnetic clusters formed by doped holes.

| Abstract: | A new low-temperature anomalous magnetism at about 29 K for the oxygen-doped (Eu1-x, Yx)2CuO4 and Sm2CuO4, prepared under high pressure, has been investigated. This anomaly originated from different mechanisms to weak ferromagnetism
(WF) behavior of T′ phase, and should be assigned to the ferromagnetic clusters formed by doped holes. |
