Abstract
We report the low-temperature properties of SrNd2O4, a geometrically frustrated magnet. Magnetization and heat capacity measurements performed on polycrystalline samples indicate the appearance of a magnetically ordered state at TN = 2.28(4)K. Powder neutron diffraction measurements reveal that an antiferromagnetic state with the propagation vector q = (0 1/2 1/2 ) is stabilized below this temperature. The magnetic order is incomplete, as only one of the two Nd3+ sites carries a significant magnetic moment while the other site remains largely disordered. The presence of a disordered magnetic component below TN is confirmed with polarized neutron diffraction measurements. In an applied magnetic field, the bulk property measurements indicate a phase transition at about 30 kOe. We construct a tentative H-T phase diagram of SrNd2O4 from these measurements.
