A heat treatment device in a magnetic field (magnetic field heat treatment furnace, magnetic field annealing furnace) is a device that performs heat treatment while applying a magnetic field to the sample. Heat treatment in a magnetic field plays an important role not only in the development and exploration of magnetic materials but also in improving the performance of magnetic devices such as magnetic sensors, magnetic memory (MRAM), and HDDs during the manufacturing process. Tōei Kagaku Sangyō, a manufacturer specializing in magnetics, provides users with the optimal heat treatment environment in a magnetic field.

The "High Sensitivity Thin Film Magnetostriction Measurement Device" is a measurement device that allows for the measurement of supermagnetic thin films with a thickness of a few nanometers while maintaining a compact body. By adopting a newly developed ultra-high sensitivity long optical path unit, it has become possible to perform even higher sensitivity measurements with good reproducibility. Please utilize it for zero magnetostriction measurements of ultra-thin films such as GMR and TMR in recent times. 【Features】 ■ Compact ■ High reproducibility ■ High sensitivity measurement *For more details, please contact us or download the catalog.
