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…
