The reversal of the spontaneous exchange bias effect and zero-field-cooling magnetization in La1.5Sr0.5Co1−xFexMnO6: the effect of Fe doping
TL;DR: It is proposed that the spin state transition caused by inhomogeneity is considered to play an important role in the reversal of the magnetization and the spontaneous exchange bias (SEB) with the doping concentration from magnetic measurements.

Strain coupling and acoustic attenuation associated with glassy magnetic phase transitions in the disordered double perovskite La 2 FeMnO 6
TL;DR: In this paper, the magnetoelastic coupling mechanism appears to involve local spin states with strain relaxation enhanced by changes in local electronic structure and local heterogeneity in the strain state, such as at ferroelastic twin walls, will contribute to magnetic heterogeneity of these materials.

Harikrishnan S. Nair,Diptikanta Swain,N Hariharan,Shilpa Adiga,Chandrabhas Narayana,Suja Elzabeth +5 more
TL;DR: In this article, the Griffiths phase-like features and spin-phonon coupling effects observed in Tb(2)NiMnO(6) are reported and a negative deviation from ideal Curie-Weiss law exhibited by 1/chi(T) curves and less-than-unity susceptibility exponents from the power-law analysis of inverse susceptibility are reminiscent of Griffiths phases.
