Introduction of sample angular rotation device (ES-12010)
Sample angular rotation device (ES-12010)
Here we introduce a sample angular rotation device that can perform ESR measurements while changing the angle of a single crystal sample automatically. This device, controlled by ESR spectrometer, can set the sample placed in the cavity at any angle. It can be used in combination with a variable temperature controller (ES-13060DVT5) or a variable liquid helium temperature system (ES-CT470/BU).
- Rotation angle: 0 to 360°
- Minimum angle resolution: 0.06°
- Universal cavity (ES-UCX2)
- Transmission cavity (ES-MCX3B)
- Control program
- Sample rod (O.D. 3 mm / O.D. 4.75 mm)
- Sample holder (for O.D. 3 mm / O.D. 4.75 mm)
Example of ESR measurement
Figures 1 and 2 show ESR spectra using a ruby single crystal at room temperature while rotating the angle in 1° increments. It is known that ruby is a crystal composed of Al2O3 as a main component, and a small amount of Cr2O3 where Cr3+ is substituted to Al3+. Therefore, in the ESR measurement of ruby, Cr3+ is observed. From the angular dependence of the Cr3+ signal, information about the electronic state and crystal field around Cr3+ is estimated.
