Magnetic susceptibility and heat capacity investigations of the unconventional spin-chain compound Sr3CuPtO6
S. Majumdar, V. Hardy, M. R. Lees +3
The Heisenberg spin chain compound Sr3CuPtO6 is investigated by magnetic susceptibility and heat capacity measurements. Sr3CuPtO6 has an unconventional chain structure in the sense…
Magnetic phase diagram of the antiferromagnetic pyrochlore Gd2Ti2O7
O. A. Petrenko, M. R. Lees, G. Balakrishnan +1
Gd2Ti2O7 is a highly frustrated antiferromagnet on a pyrochlore lattice, where apart from the Heisenberg exchange the spins also interact via dipole-dipole forces. We report on low…
Field-Induced Magnetization Steps in Intermetallic Compounds and Manganese Oxides: The Martensitic Scenario
V. Hardy, S. Majumdar, S. Crowe +9
Field-induced magnetization jumps with similar characteristics are observed at low temperature for the intermetallic germanide Gd5Ge4and the mixed-valent manganite Pr0.6Ca0.4Mn0.96…
Oxygen Moment Formation and Canting in Li2CuO2
E. M. L. Chung, G. J. McIntyre, D. McK. Paul +2
The possibilities of oxygen moment formation and canting in the quasi-1D cuprate Li2CuO2 are investigated using single crystal neutron diffraction at 2 K. The observed magnetic int…
The role of electronic correlations on the phonon modes of MnO and NiO
E. M. L. Chung, D. McK. Paul, G. Balakrishnan +3
The possibility of magnetic-order induced phonon anisotropy in single crystals of MnO and NiO is investigated using inelastic neutron scattering. Below Tn both compounds exhibit a…
Specific heat and magnetization study on single crystals of a frustrated, quasi one-dimensional oxide: Ca3Co2O6
V. Hardy, S. Lambert, M. R. Lees +1
Specific heat and magnetization measurements have been carried out under a range of magnetic fields on single crystals of Ca3Co2O6. This compound is composed of Ising magnetic chai…
