Strongly anisotropic magnetocaloric effect in a dipolar magnet LiGdF
G. Iu. Andreev, I. V. Romanova, O. A. Morozov +4
We report the detailed study of the magnetocaloric effect (MCE) in a dipolar-Heisenberg magnet LiGdF using magnetization measurements performed on a single crystal sample. Entr…
Microscopic spin Hamiltonian for a dipolar-Heisenberg magnet LiGdF4 from EPR measurements
S. S. Sosin, A. F. Iafarova, I. V. Romanova +5
Low-temperature electron paramagnetic resonance measurements are performed on single crystals of LiY_{1-x}Gd_xF_4 with weak x=0.005 and moderate x=0.05 concentration of Gd ions. Mo…
Novel magnetic phase in a weakly ordered spin-1/2 chain antiferromagnet SrCuO
E. G. Sergeicheva, S. S. Sosin, D. I. Gorbunov +3
We present the magnetic phase diagram of a spin-1/2 chain antiferromagnet SrCuO studied by ultrasound phase-sensitive detection technique. We observe an enhanced effect of…
Magnons in SrCuO: possible evidence for Goldstone-Higgs interaction in a weakly ordered spin-1/2 chain antiferromagnet
E. G. Sergeicheva, S. S. Sosin, L. A. Prozorova +2
The Goldstone theorem mandates that a spontaneous symmetry breaking entails the emergence of gap(mass)less excitations. In the case where a rotational invariance of a system of spi…
Suppression of 3D-ordering by defects in the frustrated chain magnet LiCuVO
L. A. Prozorova, S. S. Sosin, L. E. Svistov +6
We report on a heat capacity study of high quality single crystal samples of \lcvo\ -- a frustrated spin chain system -- in magnetic field amounting to 3/4 of the saturatio…
Novel magnetic phases in a Gd2Ti2O7 pyrochlore for a field applied along the [100] axis
O. A. Petrenko, M. R. Lees, G. Balakrishnan +2
We report on longitudinal and transverse magnetisation measurements performed on single crystal samples of Gd2Ti2O7 for a magnetic field applied along the [100] direction. The meas…
