Abstract：The doping effects on the frustration and the magnetic properties in hexagonal compounds of YMn0.9A0.1O3 (A=Al, Fe and Cu) are investigated. Experimental results indicate that both the non-magnetic and magnetic ion dopants lead to the increase of magnetic moments and the decrease of the absolute value of Curie–Weiss temperature (|θCW|). Compared with pure YMnO3, the geometrical frustration of YMn0.9A0.1O3 is greatly suppressed and the magnetic coupling in that exhibits dopant-dependent. In addition, for the doped YMn0.9A0.1O3, the antiferromagnetic transition temperature (TN) is also suppressed slightly, which shows an abnormal dilution effect and it may be ascribed to the reduction of frustration due to the chemical substitution.
