Abstract:
We present a magnetic phase diagram of rare-earth pyrochlore Yb2Ti2O7 in a \langle{}111̊angle{} magnetic field. Using heat capacity, magnetization, and neutron scattering data, we show an unusual field dependence of a first-order phase boundary, wherein a small applied field increases the ordering temperature. The zero-field ground state has ferromagnetic domains, while the spins polarize along \langle{}111̊angle{} above 0.65 T. A classical Monte Carlo analysis of published Hamiltonians does acc...     »
