Evolution of the Field Induced Magnetic Structure in Neodymium Tetraboride
We are proposing to investigate the field induced magnetic structure and diffuse scattering of NdB4. NdB4 is a rare experimental realisation of the Shastry-Sutherland lattice, a frustrated lattice with an exact ground state solution. NdB4 shows a range of novel and unusual properties believed to arise due to the competition between the magnetic and quadrupolar interactions. We have grown single crystals of NdB4 and characterised them using magnetisation measurements. We have also performed a neutron experiment on D10 in order to determine the magnetic structure in zero field. Our refinements have suggested the low temperature magnetic structure is helical. This experiment will give us a fuller understanding of the magnetisation process in NdB4.
