摘要：

Magnetic, thermal and electrical properties of the Y0.95Sc0.05(Mn(1-x)Al(x))2 pseudo-binary system have been studied. The ground state of Y0.95Sc0.05Mn2 is paramagnetic with quantum spin fluctuations of large amplitude. By substituting Al for Mn, X-T curves exhibit a maximum due to a spin glass freezing and the enhanced gamma value for x = 0 decreases rapidly with x. These observations are interpreted as a result of the spin liquid to spin glass transition by impurity effects in a frustrated system.
