| contents | The investigation of transport characteristics in high-temperature superconductors under magnetic fields is one of the most important topics in condensed matter physics and transport applications. For YBa$_2$Cu$_3$O$_7$ (YBCO), the measurements of magnetoresistance under a high magnetic field are technically challenging because the required magnetic field ($B$) to suppress the superconductivity is 100~T class. The low temperature (from 52 to 150 K) longitudinal magnetoresistance ($B$$\parallel$ab-plane$\parallel$$J$, where $J$ is an electrical current) was measured up to 103~T in optimally doped YBCO thin films. A radio frequency reflection method and the single-turn coil technique were employed. The electrical resistivity $ρ_{ab}$ exhibited a non-saturating magnetoresistance behavior until the highest field region, with the slope $β(=d ρ/d B)$ showing a pronounced deviation compared to the transverse magnetoresistance ($B$$\parallel$c-axis) case. These findings suggest a potential contribution due to the non-orbital origin in the high field phase of YBCO, because the quasiparticle orbital motion is expected to be absent in the longitudinal magnetoresistance. |
