Determination of magnetic superstructures in HoTe3
Rare-earth layer chalcogenides of type RTe3 (R: Ce, Ne, Gd, Tb, Dy, Ho, Er, Tm) are prominent examples which undergo charge (CDW) and magnetic order and superconductivity under pressure. In our preliminary experiments on IN22 (CRG-2702 and 7-02-188) and on THALES (4-01-1670), we found that charge and magnetic orders in TbTe3 are highly entwined. However, while TbTe3 is remarkable in having three very closely spaced transitions between 5.3 and 5.8 K, all of the compounds in the series exhibit two successive magnetic transitions. The goal of the proposed experiment is to determine for the first time the magnetic superstructures in the parent compound HoTe3 ((Tmag1= 3.25K and Tmag2= 2.87K): modulations vectors (incommensurate or commensurate) below TN, temperature dependence and collection of magnetic intensities aiming at a magnetic structure refinement. These measurements are of a great importance with respect to the joint proposal on THALES entitled żDetermination of the magnetic excitations in the charge density wave compound HoTe3 by inelastic neutron scatteringż. To that end we apply for 6 days on the 4-circle diffractometer D10 featuring low background and high resolution.
