“…Just as in prototypical spin glass and structural glasses, the elements of frustration and disorder lead to non-ergodocity, history dependence, frequency dependent relaxation behavior, and the presence of inhomogeneous nano clusters or domains. …”

“…Furthermore, the collective Ca(2+) spiking activity in islet shows on-off intermittency with scaling of spiking amplitudes, and stimulus dependent autoassociative memory features. We use a simple spin glass-like model for the functional network of a β-cell collective to describe these findings and argue that Ca(2+) spike trains produced by collective sensing of β-cells constitute part of the islet metabolic code that regulates insulin release and limits the islet size.…”

“…Also, no significant MTEP is observed in CuGa(1-x)Mn(x)Te(2) and Bi(1.99)Cr(0.01)Te(3), for which Kondo-type interaction between magnetic moments and carriers prevails. In contrast, spin glass CuCrTiS(4) exhibits negative MTEP like in ferromagnetic ruthenates and paramagnetic misfit cobaltites. …”

“…The low-temperature magnetic state for higher La compositions (1.5 [Formula: see text] [Formula: see text] [Formula: see text] 1.99) culminates into a spin-glass like state below 6 K. Cole–Cole plot and Casimir-du Pr[Formula: see text] fit shows the narrow distribution of spin relaxation time in these compounds.…”

“…Moreover, there was a gradual increase in both saturation magnetization (M(s)) and magnetic moment ([Formula: see text]) with increasing amount of Ga(3+) till x = 0.6 and then a progressive decline with increases in the x content; this was ascribed to the spin-glass-like behavior at low temperatures. It was detected that magnetic properties correlate well with crystallite/particle size, cation distribution, and anisotropy.…”

The Super Spin Glass Tb [Formula: see text] Gd [Formula: see text] Cu [Formula: see text] nanoparticles ([Formula: see text] absent, and [Formula: see text] 20 K) are considered an intermediate disposition in between those two extremes, according to their enhanced random-bond contribution to frustration.…”
