Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The occurrance of ferromagnetism for the t-J model on a square lattice is investigated using high-temperature series for the Helmholtz free energy F and the uniform magnetic susceptibility 0. For J=0 fourteenth-order series have been calculated for F and 0 and we estimate F(T=0) to find the ground-state energy. A region of fully polarized ferromagnetism is found for J<0. A ferrimagnetic region is observed for larger J/t where 0 is divergent, but F(T=0) is below that of spinless fermions. Our results do not support Nagaokas theorem at a thermodynamic density of holes. © 1992 The American Physical Society.
