| Abstract | |
Magnetic properties of dilute single crystals of Gd1-xYxB4 (x = 0, 0.2, and 0.4) were systematically studied. These antiferromagnetic Shastry-Sutherland compounds display a remnant magnetization M-R when field cooled below the Neel temperature T-N. The magnitude of M-R at low magnetic fields is magnetic field dependent, increasing with increasing magnetic fields, and it saturates for H <= 30 Oe. The M-R(T) data for both x = 0.2 and 0.4 compositions overlap, and the remnant magnetization follows a universal behavior. We argue that these findings are explained by taking into account the formation of magnetic domains within the crystals, originating from the dilution of a magnetically frustrated, antiferromagnetic sublattice.
