High-quality　flexible　magnetic　oxide　thin　films　have　promoted　a　wide　range　of　potential　applications　in　spintronic　devices　due　to　their　unique　physical　properties.　To　obtain　the　optimized　microwave　magnetism　for　future　all-oxide-based　spintronic　applications,　high-quality　oxide　materials　with　excellent　epitaxial　quality　as　well　as　specific　bending　properties　related　to　ferromagnetic　resonance　are　high　in　demand.　Here,　(001)-oriented　La0.67Sr0.33MnO3　epitaxial　thin　films　with　different　thicknesses　have　been　grown　and　subsequently　transferred　onto　flexible　poly(dimethylsiloxane)　substrates.　The　microwave　magnetisms　of　these　film　samples　have　been　investigated　under　various　bending　states.　Under　bending,　the　ferromagnetic　resonance　lineshape　of　the　film　gradually　transits　from　a　single　mode　to　a　superposition　of　multimodes,　possibly　because　of　the　uneven　distribution　of　magnetization　in　the　bending　film　at　X-band.　This　phenomenon　is　more　apparent　when　the　direction　of　the　applied　magnetic　field　goes　close　to　the　out-of-plane　of　the　film.　Hence,　an　integration　of　invariable　and　continuous　tuning　of　ferromagnetic　resonance　field　under　various　mechanical　bending　can　be　achieved　in　one　same　sample　by　just　tuning　the　direction　of　the　applied　magnetic　field,　which　reveals　that　the　flexible　La0.67Sr0.33MnO3　thin　films　have　huge　potential　in　the　applications　in　future　flexible　multifunctional　devices.
