Magnetic susceptibility and magnetization measurements before and after irradiation were carried out using a Quantum Design MPMS 7 superconducting quantum interference device (SQUID) magnetometer. A sample (≃ 0.1 mg) supported on a commercial transparent adhesive tape was placed on the edge of an optical fiber. As exciting light sources, the OPO laser (Surelight OPO; HOYA-continum, 410 < λ < 2500 nm) pumped by Nd-YAG laser (Surelight II; HOYA-continum, λ = 355 nm, repetition = 10 Hz, pulse width = 5 ns) was used.
