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 transport properties of ferromagnetic compound CeMn 2 Ge 2 have been systematically studied by magnetic resistivity measurements. Strikingly, it has been found that CeMn 2 Ge 2 compound displays a giant topological Hall effect (THE) about 0.8 μΩ·cm with 0.45 T magnetic field under 220 k. THE appears in a wide temperature range between 70 and 310 K in a magnetic field region, and could even appear in a zero magnetic field at room temperature. The magnetoresistance curves present gradual change with kinks which have relation to magnetic transitions. Moreover, these results show that topologically protected spin texture may exist in CeMn 2 Ge 2 ferromagnetic compound.
