Title:
MAGNETIC ANISOTROPY AND SPIN EXCITATIONS IN RARE-EARTH MANGANITES RMn03 (R = Pr, Nd)

Abstract:
We revealed strong anisotropy of the magnetic susceptibility
of PrMnO3 and NdMnO3 single crystals and qualitatively
different temperature dependences of their spontaneous
weak-ferromagnetic moments (σ0||c-axis), which are due to the
anisotropic contributions of the corresponding rare-earth ions.
In submillimeter transmission spectra (ν = 2-33cm1)
we observed several absorption lines identified as antiferromagnetic resonance
(AFMR) modes of Mn ions and rare-earth modes associated
with the electronic transitions inside (a) the fundamental Pr3+
quasi-doublet split by the crystal field (~14.5cm-1) and (b)
the Kramers Nd3+ doublet split by the exchange field of the Mn
subsystem (~14cm-1). The observed static and dynamic magnetic
properties of PrMnO3 and NdMnO3 are analyzed using the
single-doublet approximation for Nd3+ (Pr3+) ions,
and the corresponding components of g tensors of the doublet (quasi-doublet) and their splitting in
the exchange (crystal) field are determined from comparison with experiment.
