The torque-induced variation of damping constant of magnetization can be foreseen from the change of the linewidth of ferromagnetic resonance spectrum. The Oersted torque (\u03c4Oe) and current-induced torque (\u03c4C) are induced by charge current; while the spin-orbit torque (\u03c4SO) and field-like torque (\u03c4FL) are induced by spin current. However, the torque effects often were hindered due to the heating-induced artifacts. In this work, we particularly pay attention to minimize the Joule heating effects in order to investigate the intrinsic torque effects in cobalt (Co)\/platinum (Pt) bilayer with an applied charge current ranging from \u221260 to 60 mA. In this range, the Oersted field is estimated as 0.25 Oe which is much smaller than the experimental result of \u0394Hr (\u223c0.7 Oe), implying some contribution from the spin-current induced field like torque. The current-polarization-induced asymmetry of linewidth \u0394W, \u0394W\u2261W+Jc\u2212W\u2212Jc, increases from 0 to 0.15 with Jc changing from 0 to 60 mA, which is attributed to the spin-orbit torque.<\/jats:p>","DOI":"10.1063\/1.5129732","type":"journal-article","created":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T13:43:35Z","timestamp":1577108615000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Detection of torque effects in Co\/Pt via ferromagnetic resonance"],"prefix":"10.1063","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7495-3598","authenticated-orcid":false,"given":"Yi-Chien","family":"Weng","sequence":"first","affiliation":[{"name":"Graduate Institute of Applied Physics, National Taiwan University 1 , Taipei 10617, Taiwan"},{"name":"Center for Condensed Matter Sciences, National Taiwan University 2 , Taipei 10617, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4435-5949","authenticated-orcid":false,"given":"C.-T.","family":"Liang","sequence":"additional","affiliation":[{"name":"Graduate Institute of Applied Physics, National Taiwan University 1 , Taipei 10617, Taiwan"}]},{"given":"J.
