Spin correlations and magnetonuclear cross-correlation in Sm(Sr)-Mn-O perovskites in the low-temperature phase
1999
The results of measurements of spin correlations and magnetonuclear cross-correlations (MNCCs) in the system 154Sm1−xSrxMnO3 with the perovskite structure (x=0.25,0.4) in the low-temperature phase in magnetic fields 0neutron scattering method (SAPNS). It is shown that ferromagnetic correlations with a scale of 180–250 A and MNCCs characterizing the intercoupling of the magnetic and lattice subsystems on this scale exist in the system. It is found that in the low-temperature phase the system exhibits spin-glass properties.
