Phase diagram of diluted Ising ferromagnet LiHoxY1-xF4

Conradin Kraemer, Bastien Dalla Piazza, Julian Piatek, Henrik Moodysson Rønnow, Neda Nikseresht Ghanepour, Ivan Kovacevic, Peter Babkevich

We present a systematic study of the phase diagram of LiHoxY1-xF4 (0.25

Neutron spectroscopic study of crystal-field excitations and the effect of the crystal field on dipolar magnetism in LiRF4 (R = Gd, Ho, Er, Tm, and Yb)

Conradin Kraemer, Bastien Dalla Piazza, Henrik Moodysson Rønnow, Ivan Kovacevic, Peter Babkevich

We present a systematic study of the crystal-field interactions in the LiRF4 (R = Gd, Ho, Er, Tm, and Yb) family of rare-earth magnets. Using detailed inelastic neutron scattering measurements, we have been able to quantify the transition energies and wave ...

Dipolar Antiferromagnetism and Quantum Criticality in LiErF4

Conradin Kraemer, Bastien Dalla Piazza, Julian Piatek, Henrik Moodysson Rønnow, Neda Nikseresht Ghanepour, Nikolay Tsyrulin, Gabriel Aeppli

Magnetism has been predicted to occur in systems in which dipolar interactions dominate exchange. We present neutron scattering, specific heat, and magnetic susceptibility data for LiErF4, establishing it as a model dipolar-coupled antiferromagnet with pla ...

Magnetic excitations near the quantum phase transition in the Ising ferromagnet LiHoF4

Conradin Kraemer, Henrik Moodysson Rønnow

Effective-medium theory and inelastic neutron scattering are used to study the magnetic excitations in the Ising ferromagnet LiHoF4 near its magnetic-field-induced quantum phase transition (QPT). As expected, the dominant mode softens at the QPT, but reach ...
