Neutron thermo-diffraction experiments have been carried out to investigate the concomitant coupling between spin and lattice degrees of freedom in detail. Although it seems that the alloy entirely changes from the AFM to FM order in a very narrow temperature range (with a hysteresis of about 6 K), evidence of AFM order persists even 70 K above the first-order phase transition, suggesting a kinetic arrest of the AFM phase during both heating and cooling procedures.

Currently, solution-based processing of graphene and other similar van der Waals solids favor toxic solvents such as NMP, limiting their use for biosensing. However, with the use of Cyrene, bio-compatible printable devices are possible, and studies have already demonstrated its use in temperature and other biosensing methods through screen-printing. Screen-printing unfortunately often requires masks that constrain the minimum acquirable feature size to be above hundreds of centimeters and wastes material, adding to process complexity and cost. Conversely, inkjet-printing is an attractive alternative for the maskless patterning of hierarchically assembled structures, with micron length scales attainable. Graphene's high conductivity positions it ideally for long-wear sensors such as dry electrodes or respiration monitors. Here, we demonstrate the potential of Cyrene-based graphene inks through few-layer inkjet printing on flexible substrates for the first time, to produce non-toxic conductors toward a strain-mediated mechanism for biosensing, used to detect bodily motion for wearable electronics. The challenges overcome in this study include engineering ink chemistry and printing parameters such that Cyrene's relatively high viscosity compared to typical inkjet solvents, still allows for droplet ejection in a conventional material printer, yielding well-resolved clean line-edges in contrast to other solvents that exhibit diffuse line-edges possibly from stray droplets and ink-splashing. Temperature-dependent transport measurements on the inkjet-printed Cyrene-based graphene films showed the conductivity to be largely temperature-invariant but at lower temperatures below 100 K, conductivity decreased, likely as a result of increased inter-membrane separation arising from thermal contraction. Additionally, temperature-dependent Raman spectroscopy showed the red-shift in the G-band, 2D-band and D-band peaks, as temperature increased.

Nonetheless, the utilization of these optical materials is significantly constrained by the intricate synthesis process and weak photochromic contrast. Herein, a one-step microwave-assisted solid-state method is adopted to prepare sodalites and optimize their photochromic performance. The results show that the sample can be synthesized through only 16-minute microwave radiation, greatly simplifying the preparation process. Notably, the maximum photochromic contrast of sodalites is enhanced from 13.8% to 26.9% through the partial substitution of Cl with S ions. In addition, optical spectroscopy and electron spin resonance experiments are performed to investigate the influence of traps on the photochromic behavior. It was found that the photochromic behavior in sodalites is mainly determined by traps with an energy depth around 0.788 eV. The activation energy of these traps is determined by the host and the corresponding preparation approach. Finally, sodalite-based compounds are fabricated into fibers for clothing decoration demonstration.
