“…17,18 As noticed earlier, they strongly differ from those of the hexagonal RMnO 3 series, which scale from one compound to another. 24,25 The refined atomic positions reported in Table I agree with previous determinations from x-ray diffraction. 17 The thermal variation of the positional parameter x of the Mn sites is reported in Fig.…”

InMnO 3 is a peculiar member of the hexagonal manganites h-RMnO 3 (where R is a rare-earth metal element), showing crystalline, electronic, and magnetic properties at variance with the other compounds of the family. We have studied high quality samples synthesized at high pressure and temperature by powder neutron diffraction. The position of the Mn ions is found to be close to the threshold x = 1/3 where superexchange Mn-Mn interactions along the c axis compensate. Magnetic long-range order occurs below T N = 120(2) K with a magnetic unit cell doubled along c, whereas short-range two-dimensional dynamical spin correlations are observed above T N . We propose that pseudodipolar interactions are responsible for the long period magnetic structure.

“…The antiferromagnetic spin-ordering transition in the a - b plane of the Mn 3 + spins occurs at Néel temperature ~70–130 K, depending on the rare earth ion333435. Including the antiparallel and parallel orientation of corresponding Mn 3 + spins at z = 0 and z = c /2 in the unit cell, there are a few different possible magnetic symmetries18.…”

Spin-wave (magnon) scattering, when clearly observed by Raman spectroscopy, can be simple and powerful for studying magnetic phase transitions. In this paper, we present how to observe magnon scattering clearly by Raman spectroscopy, then apply the Raman method to study spin-ordering and spin-reorientation transitions of hexagonal manganite single crystal and thin films and compare directly with the results of magnetization measurements. Our results show that by choosing strong resonance condition and appropriate polarization configuration, magnon scattering can be clearly observed, and the temperature dependence of magnon scattering can be simple and powerful quantity for investigating spin-ordering as well as spin-reorientation transitions. Especially, the Raman method would be very helpful for investigating the weak spin-reorientation transitions by selectively probing the magnons in the Mn3+ sublattices, while leaving out the strong effects of paramagnetic moments of the rare earth ions.

“…The magnetic susceptibility of ScMnO 3 exhibits a different anomaly at with a field-dependent irreversible behavior (difference between field-cooled and zero field-cooled data) below and an obvious magnetization hysteresis loop at the lowest temperatures [90,95,178,179]. This has been interpreted as a weak ferromagnetic moment associated with the magnetic order below .…”

Hexagonal manganites belong to an exciting class of materials exhibiting strong interactions between a highly frustrated magnetic system, the ferroelectric polarization, and the lattice. The existence and mutual interaction of different magnetic ions (Mn and rare earth) results in complex magnetic phase diagrams and novel physical phenomena. A summary and discussion of the various properties, underlying physical mechanisms, the role of the rare earth ions, and the complex interactions in multiferroic hexagonal manganites, are presented in this paper.
