The Magneto Optical Cryostat is a state-of-the-art scientific instrument designed to facilitate advanced research in the field of quantum materials. It offers exceptional temperature stability, high magnetic field capabilities, and precise optical access, making it an ideal choice for studies requiring controlled cryogenic environments combined with magnetic field manipulation. This cryostat is engineered to meet the demanding needs of researchers investigating the fundamental properties and behaviors of quantum materials under extreme conditions.
One of the standout features of this Magneto Optical Cryostat is its remarkable temperature stability. For temperatures at or below 20 K, it maintains an impressive stability of ±0.2%, ensuring that experimental conditions remain consistent and reliable throughout the duration of sensitive measurements. For temperatures above 20 K, the device offers even greater precision with a stability of ±0.02%. This level of control is crucial for experiments involving quantum materials, where minute temperature fluctuations can significantly impact the observed phenomena.
Vibration control is another critical aspect of this cryostat's design. The sample stage vibration is limited to ≤±20 nm, minimizing mechanical disturbances that could otherwise compromise the integrity of high-precision optical and magnetic measurements. This low vibration environment supports high-resolution data acquisition and enhances the reproducibility of experimental results.
The sample space within the cryostat is generously sized, featuring an 89 mm diameter and an 88 mm height. This ample volume accommodates a variety of sample sizes and experimental setups, providing researchers with the flexibility required to explore diverse quantum materials and complex experimental configurations. The spacious sample chamber also facilitates the integration of additional instrumentation and measurement devices as needed.
Central to the cryostat's functionality is its conical split-coil superconducting magnet, oriented vertically to deliver a high magnetic field with exceptional uniformity and stability. The magnet produces a field strength of ±1 T with a uniformity of ±0.3% within a 3 cm spherical area, ensuring consistent magnetic conditions throughout the sample region. The magnetic field variation speed is calibrated to reach 0.7 T in under 30 minutes, allowing for efficient adjustment of experimental parameters without compromising stability. This high magnetic field capability is indispensable for probing the magnetic and electronic properties of quantum materials, enabling researchers to uncover new insights into their behavior under strong magnetic influences.
Optical access is facilitated by a carefully designed arrangement of optical windows. The cryostat features one top window with a diameter of 50 mm and a clear aperture of 44 mm, along with seven side windows each measuring 40 mm in diameter with a clear aperture of 26 mm. These windows provide extensive optical pathways for laser beams, spectroscopy, and other optical measurement techniques crucial for examining quantum materials. The large and clear apertures ensure minimal optical distortion and maximum transmission, thereby enhancing the accuracy of optical experiments conducted within the cryogenic and high magnetic field environment.
In summary, the Magneto Optical Cryostat combines superior temperature stability, minimal vibration, a spacious sample chamber, and a high magnetic field generated by a conical split-coil superconducting magnet with excellent uniformity. Coupled with multiple high-quality optical windows, it provides a versatile and robust platform for advanced research into the properties of quantum materials. This instrument is particularly suited for scientists seeking to explore the interplay between temperature, magnetic fields, and optical properties in quantum systems, making it an invaluable tool for pushing the frontiers of condensed matter physics and material science.
