Magnetic field inducing co-existing antiferromagnetic phases in SrYb2O4 (Continuation)
SrYb2O4 is an insulating magnet, consisting of two types of zigzag chains running along the c-axis and forming a honeycomb structure in the ab-plane. The similar first and second-neighbor distances suggest high geometrically frustrated magnetic interactions. This frustration sums up to strong single ion anisotropy to produce a highly degenerate ground state manifold reflected by a very complex and anisotropic magnetic phase diagram. Despite of SrYb2O4 having a CurieWeiss temperature of −110K, the compound only orders at 0.9K at zero field, the magnetic structure is found to be noncollinear with a reduction of the ordered magnetic moment from the full ionic moment. Due the competition between frustration and high single ion anisotropy, SrYb2O4 has very rich and complex magnetic phase diagram. The different magnetic phases formed when applying a field along the c-axis have been investigated by neutron diffraction on D10. However, due to technical issues with the dilution refrigerator and an unexpected reactor shut down a completed data set was not possible to be acquired. Here, we propose to continue with this experiment.
