Spin-lattice coupling, frustration and magnetic order in multiferroic RMnO3
X. Fabreges, S. Petit, I. Mirebeau +5
We have performed high resolution neutron diffraction and inelastic neutron scattering experiments in the frustrated multiferroic hexagonal compounds RMnO3 (R=Ho, Yb, Sc, Y), which…
Magneto-elastic coupling in hexagonal YMnO_3
Mario Poirier, Francis Laliberte, Loreynne Pinsard +1
We report an ultrasonic investigation of the elastic moduli on a single crystal of hexagonal YMnO_3 as a function of temperature. Stiffening anomalies in the antiferromagnetic Néel…
Evidence of ultra-slow polaron dynamics in low-doped manganites from 139La NMR-NQR and muon spin rotation
G. Allodi, M. Cestelli Guidi, R. De Renzi +2
We report a 139La NMR investigation of low-doped insulating manganite samples (LaMnO(3+y) and La(1-x)Ca(x)MnO(3+y)) as a function of temperature. A volume fraction with fast nuclea…
Approach to the metal-insulator transition in La(1-x)CaxMnO3 (0<x<.2): magnetic inhomogeneity and spin wave anomaly
G. Biotteau, M. Hennion, F. Moussa +4
We describe the evolution of the static and dynamic spin correlations of LaCaMnO, for x=0.1, 0.125 and 0.2, where the system evolves from the canted magnetic state…
Staggered magnetization, critical behavior and weak ferromagnetic propert ies of LaMnO by muon spin rotation
M. Cestelli Guidi, G. Allodi, R. De Renzi +4
We present a study of a microtwinned single crystal of LaMnO by means of implanted muons. Two muon stopping sites are identified from the symmetry of the internal field in the…
rf susceptibility of La_{1-x}Sr_{x}MnO_{3} single crystals : magnetic signatures of structural changes
P. V. Parimi, H. Srikanth, M. Bailleul +4
A sensitive tunnel diode oscillator (TDO) operating at 4MHz is used to probe the dynamic response of La_{1-x}Sr_{x}MnO_{3} single crystals for x=0.125,0.175,0.28 and 0.33 doping. S…
