Search for superstructure reflections in the magnetization plateau phases of TbB4
TbB4 has a tetragonal structure (P4/mbm) in which the network of Tb3+ ions lying in the c-plane is equivalent to the geometrically frustrated Shastry-Sutherland lattice (SSL). In zero-field, two successive antiferromagnetic transitions occur at TN1=44 K and TN2=24 K. Upon the application of a magnetic field along the c-axis, TbB4 is known for its devil-staircase-like magnetization process, stabilizing successive magnetization plateau phases for fields 16 ¿ mu0H ¿ 28 T. Thanks to recent single crystal neutron diffraction studies performed in pulsed magnetic field up to 35 T, it has been possible to propose several magnetic models for the three magnetization plateau phases M/MS = 2/9, 1/3 and ½ in agreement with the observed intensities of three integer Bragg peaks. In order to distinguish those models, we propose now to use the same experimental set-up at 2 K to search for their characteristic superstructure reflections at the positions (d d 0), (0 d 0) and (0 0 d), with d being 1/9, 1/3 or ½ (depending on M/MS).
