Abstract
After many experimental attempts, understanding how competing interactions occur in dimensional antiferromagnets remains to be determined. Another magnetic model, like the two-dimensional (2D) S=1 J1-J2, focuses on the J1/J2 ratio. This model will clarify how quantum tricritical points separate Neel and stripe phases. However, some experimental procedure has yet to be able to test this model. Therefore, this research project will mainly focus on utilizing zero neutron diffraction (ND) to identify the ground state magnetic structure of a NiF2(H2O)2(3-CN-py)2 that can resemble this model. In order to lessen the incoherent background scattering, D2O will be used in replace of H2O. The outcome of this project is to use the ground state magnetic structures of this compound and combine this with field-dependent SQUID data to create an enthalpy versus temperature phase diagram. Knowing the J1/J2 ratio, magnetic structure, and order parameter on the compound, thus theorize there will be unusual spin configurations.
