Multi-band superconductivity in LaFeAsO_{0.9}F_{0.1} single crystals probed by high-field vortex torque magnetometry

To probe manifestations of multiband superconductivity in oxypnictides, we measured the angular dependence of the magnetic torque \(\tau(\theta)\) in the mixed state of LaO\(_{0.9}\)F\(_{0.1}\)FeAs single crystals as a function of temperature \(T\) and magnetic fields \(H\) up to 18 T. The paramagne...
