Orbital magnetism: pros and cons for enhancing the cluster magnetism.

The discrepancy seen in the experimental and theoretical results on the magnetic moment of a small magnetic cluster has been attributed to the contribution arising from orbital magnetism. In this Letter we show that the magnetic states with large orbital magnetic moment are not always energetically favorable; they could, however, be realizable by coating the cluster or deposing it on appropriat...

Rewriting the lignin roadmap.

Considerable interest in lignin biosynthesis has been fueled by the many roles that lignin plays in development and in resistance to biotic and abiotic stress, as well as its importance to industry and agriculture. Although the pathway leading to the lignin polymer has been studied for decades, new insights into the enzymes of the pathway have required a complete re-evaluation of how we think l...

The magnetism of La1.2Sr1.8Mn2O7

The critical behaviour of La1.2Sr1.8Mn2O7 has been revisited by means of static macroscopic magnetic properties measurements. We present a renewed insight on its equilibrium properties near the critical point (TC ∼ 108 K) including the determination of the fundamental characteristics of a magnetic system (anisotropy, critical exponents and crossovers in the vicinity of the Curie temperature). I...
