Magnetic susceptibility of the compounds (dy<inf>x</inf>y<inf>1-x</inf>)<inf>2</inf>mo<inf>2</inf>o<inf>7</inf> in the temperature range 600-4.2 k

The magnetic susceptibilities of the compounds (DyxY1-x)2Mo2O7 for x=1.0, 0.8, 0.6, 0.4 and 0.2 have been measured in the temperature range 600-4.2 K to check whether any magnetic ordering is found at low temperatures and to separate the contributions from Dy3+ and Mo4+ to the susceptibility in the paramagnetic region. The effective magnetic moment of Dy3+ was found to be less than that of the free-ion magnetic moment and is attributed to the crystal-field splitting of the energy levels. © 1988 IOP Publishing Ltd.
