“…The amount of softening increases and is accompanied by an increase in Q −1 below ∼80 K, signifiying freezing behavior of some aspect of the microstructure. This coincides exactly with the development of short range magnetic ordering on a length scale of ∼7 Å within which Co moments are, on average, oriented antiparallel to the Er moments in a parimagnetic arrangement .…”

Ferroelastic materials can develop complex domain structures, which have properties of glassy systems (non-ergodicity, glass dynamics, glass transitions, and freezing). Four characteristic temperatures are defined for such domain glasses: the dynamical nucleation temperature T d where local correlated clusters can form glass states within a (tweed-) nano structure, T o the Vogel-Fulcher temperature of these precursor nanostructures, T pt the phase transition temperature where the (ferroelastic) transition occurs, and T K the Kauzmann temperature where the complex domain structure freezes. T d exists in most ferroelastic materials whereas the other transitions depend on the complexity of the domain patterns and hence on their thermal history. Shear collapse and rapid thermal quench of ferroelastic crystals preferentially lead to domain glasses whereas slow anneal produces mostly highly correlated pattern such as stripe patterns or single domain crystals. Domain glasses are compared with structural glasses and several examples for domain glass features are discussed.

a b s t r a c tThe longitudinal-field muon-spin relaxation (LF-mSR) technique was employed to study the spin correlations in (Mn,Fe) 2 (P,Si) compounds above the ferromagnetic transition temperature (T C ). The (Mn,Fe) 2 (P,Si) compound under study is found to show itinerant magnetism. The standard deviation of the magnetic field distribution of electronic origin increases with a decrease in temperature, which is attributed to the development of spin correlations. The anomalously low magnetic fluctuation rate is suggested to be another signature of the spin correlations. The development of pronounced magnetic fluctuations is in agreement with the observed deviation of the paramagnetic susceptibility from Curie eWeiss behavior. Our study sheds light on the magneto-elastic transition and the mixed magnetism in (Mn,Fe) 2 (P,Si) compounds.

“…This phenomenon is often referred to as Griffiths phase or Griffiths-like phase. 19,20,21,22,23,24,25,26,27,28,29,30,30,42 In general, the Griffiths phase behavior implies that elemental dilution or magnetic clusters with different size will decrease bulk ordering temperature T C from the onset (T G ) of the true paramagnetic state. Therefore, the magnetization fails to be analytical function of the field between T G and T C as the field approaches 0.…”
