    The magnetic properties of Nd2Sn2O7
    (Australian Institute of Physics, 2014-02-05) Imperia, P; Aldus, RJ; Rule, KC; Studer, AJ
    In this paper we will discuss the magnetic properties of the pyrochlore Nd2Sn2O7 as measured with the neutron scattering instruments Wombat and Taipan at the Bragg Institute neutron scattering facility. The measurements were conducted on a polycrystalline sample in zero magnetic field and 10 Tesla. The sample, loaded in OFHC copper can, was mounted into a dilution insert and measured between 340 mK and 50 K. The results indicated that the material doesn’t spontaneously magnetically order. However, upon application of the magnetic field, the sample is easily polarised. Achieving ultra-low temperature with a powder samples is a difficult task. Here we will discuss common strategies used to improve conductivity in the mK range and the implication for this particular study. The equipment available at the neutron scattering instruments of Bragg Institute for measurements in high magnetic fields and low temperature will be also illustrated.
