Metric Options: Counts1 Year3 YearSelecting 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
We have studied the magnetic and transport properties of La 0.8 Ba 0.2 MnO 3 single crystal over temperature range 77–400 K in magnetic fields up to 15 kOe. Near the Curie temperature, both the resistivity, the thermopower, and the normal Hall coefficient R 0 reach the maximal value, R 0 >0 and the Hall mobility is constant. The data indicate that the holes activated to mobility edge dominate in conduction. The singlesite polaron picture is inconsistent with our data on magnetoresistance and magnetothermopower.
