Abstract We report on the growth of CoFe$_{2}$O$_{4}$/Pt heterostructure and their magnetotransport properties. The magnetoresistance under high magnetic fields exhibits a sign change when the temperature increases from 5 K to 10 K. The anomalous Hall resistance decreases as the temperature increases. Furthermore, angle-dependent magnetoresistance indicates that the observed magnetotransport behaviors originate from the competition between the spin Hall magnetoresistance and magnetic proximity effect.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
