Magnetic Phases of Rare Earth Hexagonal Manganites
We describe the magnetic phases of hexagonal rare earth manganites RMnO3 using Landau theory. A minimal model based on four one-dimensional magnetic order parameters is developed.
متن کاملField Dependent Specific-Heat of Rare Earth Manganites
The low temperature specific heat C(H) of several rare-earth manganites (La0.7Sr0.3MnO3, Nd0.5Sr0.5MnO3, Pr0.5Sr0.5MnO3, La0.67Ca0.33MnO3, La0.5Ca0.5MnO3, La0.45Ca0.55MnO3 and La0.33Ca0.67MnO3) was measured as a function of magnetic field. We observed behaviour consistent with thermodynamic expectations, i.e., C(H) decreases with field for ferromagnetic metallic compounds by an amount which is ...
متن کاملHexagonal rare-earth manganites as promising photovoltaics and light polarizers
Hexagonal rare-earth manganites as promising photovoltaics and light polarizers" (2015). Evgeny Tsymbal Publications. 55. Ferroelectric materials possess a spontaneous electric polarization and may be utilized in various technological applications ranging from nonvolatile memories to solar cells and light polarizers. Recently, hexagonal rare-earth manganites, h-RMnO 3 (R is a rare-earth ion), h...
متن کاملLow-energy structural dynamics of ferroelectric domain walls in hexagonal rare-earth manganites
Domain walls (DWs) in ferroic materials, across which the order parameter abruptly changes its orientation, can host emergent properties that are absent in the bulk domains. Using a broadband (106 to 1010 Hz) scanning impedance microscope, we show that the electrical response of the interlocked antiphase boundaries and ferroelectric DWs in hexagonal rare-earth manganites (h-RMnO3) is dominated ...
متن کاملEffect of virtual 4d-shell excitations on rare earth spectra
Ab initio energies for electric dipole transitions 4d(S0) → 4d94f J = 1 in triply-ionized lanthanum have been calculated by constructing an effective interaction, acting within the configuration 4d94f, that incorporates effects of virtual 4d-shell excitations to all orders of perturbation. Virtual 4d-shell excitations, included within the random phase approximation, and virtual excitations to s...
