Growth, magnetic properties and Raman scattering of La2NiMnO6 single crystals
M. N. Iliev, M. M. Gospodinov, M. P. Singh +4
Millimeter size single crystals of double perovskite La2NiMnO6 (LNMO) were grown by the High Temperature Solution Growth Method. The magnetic measurements and polarized Raman spect…
Pressure induced enhancement of ferroelectricity in multiferroic MnO(=Tb,Dy, and Ho)
C. R. dela Cruz, B. Lorenz, Y. Y. Sun +5
Measurements of ferroelectric polarization and dielectric constant were done on MnO (=Tb, Dy, and Ho) with applied hydrostatic pressures of up to 18 kbar. At ambient…
Distortion-Dependent Raman Spectra and Mode Mixing in RMnO3 Perovskites
M. N. Iliev, M. V. Abrashev, J. Laverdiere +4
The polarized Raman spectra of orthorhombic RMnO3 series (R=La,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Y) were studied at room temperature. The variation of phonon frequencies with R ionic radius…
Low temperature dielectric anomalies in HoMnO_3: The complex phase diagram
F. Yen, C. R. dela Cruz, B. Lorenz +4
The dielectric constant of multiferroic hexagonal HoMnO_3 exhibits an unprecedented diversity of anomalies at low temperatures (1.8 K< T <10 K) and under external magnetic fields r…
Novel Field-Induced Phases in HoMnO3 at Low Temperatures
B. Lorenz, F. Yen, M. M. Gospodinov +1
The novel field-induced re-entrant phase in multiferroic hexagonal HoMnO3 is investigated to lower temperatures by dc magnetization, ac susceptibility, and specific heat measuremen…
Raman and Infrared-Active Phonons in Hexagonal HoMnO Single Crystals: Magnetic Ordering Effects
A. P. Litvinchuk, M. N. Iliev, V. N. Popov +1
Polarized Raman scattering and infrared reflection spectra of hexagonal HoMnO single crystals in the temperature range 10-300 K are reported. Group-theoretical analysis is perf…
