Spin dynamics of S = 1/2 Heisenberg chains with a staggered transverse field: electron spin resonance studies (Review Article)
In this article I review recent achievements on experimental studies of magnetic excitations in the copper pyrimidine
 dinitrate [PM–Cu(NO₃ )₂ (H ₂O) ₂ ]n (PM = pyrimidine), an S = 1/2 antiferromagnetic chain material
 with alternating g-tensor and the Dzyaloshinskii–Moriya interact...

| description | In this article I review recent achievements on experimental studies of magnetic excitations in the copper pyrimidine
dinitrate [PM–Cu(NO₃ )₂ (H ₂O) ₂ ]n (PM = pyrimidine), an S = 1/2 antiferromagnetic chain material
with alternating g-tensor and the Dzyaloshinskii–Moriya interaction, by means of high-field electron spin resonance
(ESR). Due to this alternation, in the 1D critical regime this material exhibits a field-induced gap. The excitation
spectrum is formed by solitons and their bound states, breathers, and can be effectively described using
the sine-Gordon model. With increasing temperature, the soliton-breather regime can be suppressed, resulting in
a substantial evolution of ESR parameters. These changes can be described using a new theoretical concept recently
proposed for S =1/2 AF chains with a staggered transverse field. High magnetic field induces a transition
into spin-polarized state with the excitation spectrum formed by magnons. Nonmonotonous behavior of the
field-induced gap is observed in the vicinity of saturation field. The experimental data are compared with results
of existing theoretical approaches, revealing an excellent agreement with the predictions.
