High field musr investigation of Shastry-Sutherland phase in Ce2-xPd2+yIn1-z

DOI

The Shastry-Sutherland lattice (SSL) can be described as a 2D square lattice built up from a network of dimers disposed orthogonally and has been observed in SrCu2(BO2)3. Recently SSL has been realised in Ce2T2X (T=transition metal and X=Sn, In) compounds, in which the Ce atoms form layers structure similar to SSL. Recently we have investigated Ce1.95Pd2.2In0.85 using musr measurements. Our zero field musr study shows two phase transitions in the relaxation rate at 1.4 and 3.6 K. In applied field up to 0.75 T we have seen same two peaks in the relaxation rate. Due to limited time we could not finish 1 T and 5 T runs. We therefore request four days of beam time on HiFi to complete our high field study on Ce1.95Pd2.2In0.85 to investigate the relaxation rate passing through the tricritical region, where two magnetic phase transitions merge as well as to stud new composition Ce1.9Pd2.4In0.7.
