Abstract Single crystals of YVO{sub 3} were grown using the floating-zone technique. YVO{sub 3} crystallizes in the orthorhombic Pbnm structure, and the structural parameters were determined by means of neutron diffraction. Using a superconducting quantum interference device magnetometer, we have studied the magnetic properties of YVO{sub 3} along the three principal directions. Our single crystal exhibits two magnetic transitions at about 115 and 75 K. For temperatures above the magnetic ordering, almost isotropic Curie{endash}Weiss behavior is found for the magnetic susceptibility. Below the ordering, however, we find a highly anisotropic response with the {ital c} axis as the easy-magnetization direction. Both magnetic phases exhibit a weak ferromagnetic component along the {ital c} axis. A complex low-field magnetization behavior indicates that YVO{sub 3} orders ferrimagnetically for temperatures between 75 and 115 K. {copyright} {ital 1999 American Institute of Physics.}
