Muon-spin relaxation investigation of magnetic bistability in a crystalline organic radical compound
We present the results of a muon-spin relaxation (SR) investigation
of the crystalline organic radical compound
4-(2-benzimidazolyl)-1,2,3,5-dithiadiazolyl (HbimDTDA), in which we demonstrate
the hysteretic magnetic switching of the system that takes place at caused by a structural phase transition. Muon-site analysis
using electronic structure calculations suggests a range of candidate muon
stopping sites. The sites are numerous and similar in energy but,
significantly, differ between the two structural phases of the material.
Despite the difference in the sites, the muon remains a faithful probe of the
transition, revealing a dynamically-fluctuating magnetically disordered state
in the low-temperature structural phase. In contrast, in the high temperature
phase the relaxation is caused by static nuclear moments, with rapid electronic
dynamics being motionally narrowed from the muon spectra
Dataset on the concentrations of anticoagulant rodenticides in raptors from the Canary Islands with geographic information
The dataset presented in this article supports "Intensive livestock farming as a major determinant of the exposure to anticoagulant rodenticides in raptors of the Canary Islands (Spain)"(Rial-Berriel et al., 2020). A Geographic Information System (GIS) analysis on the influence of the influence of livestock activity on exposure to anticoagulant rodenticides in raptors in the Canary Islands was performed. This dataset provides geographic information on the localization of each raptor (either positive or negative for anticoagulant rodenticides, n = 308), as well as the concentrations of each compound found in their livers. In addition, we present complementary analyses to those included in the main article, such as the detailed analysis of the farming activity influence on anticoagulant rodenticide exposure of raptors, by island and by raptor species.
