| contents | Tunable monochromatic magneto-transmission is one of the most established magneto-optical techniques, particularly well suited for pulsed magnetic fields. It employs fixed-wavelength monochromatic light as the probe, while the magnetic field is swept to bring the sample into resonance with the photon energy. The key component of this setup is a tunable laser system, typically consisting of a Ti:sapphire laser coupled with an optical parametric oscillator. However, such laser systems are often bulky, expensive, and inherently unstable, which significantly limits their widespread application in magneto-optical laboratories. In this work, we develop a high-accuracy, cost-effective, and compact tunable monochromatic magneto-transmission system based on a combination of a laser-driven white light source and a mini monochromator, and demonstrate its feasibility and performance in a millisecond-range pulsed magnetic field condition. To verify the accuracy of this new and simplified setup, we performed Faraday rotation measurements on the geometrically frustrated spin system CdCr2O4, as well as magneto-transmission experiments on the Shastry-Sutherland lattice antiferromagnet SrCu2(BO3)2. These results show excellent agreement with previous reports, confirming the reliability and precision of the new setup. |
