Detailed Measurements of the Crystalline Electric Field of Shastry-Sutherland Magnets Rare Earth Tetraborides
We propose to measure the crystalline electric field (CEF) levels of NdB4, ErB4 and HoB4 using IN4. These compounds belong to a family of rare earth tetraborides REB4, where the RE ions form a network that maps to the frustrated Shastry-Sutherland lattice. Magnetisation measurements of REB4 show fractional magnetisation plateaux common to all compounds, but can dramatically change between RE ions. This suggest the CEF could play an important role in the properties displayed by the REB4. This experiment will be carried out in zero applied field on powder samples. If successful further investigations into other members will likely be requested.
