title: Design of in situ sample rotation mechanism for angle-dependent study of cantilever-detected high-frequency ESR.
abstract: Cantilever detected electron spin resonance (ESR) technique is combined with a precise rotation stage for angle-dependent ESR study of a tiny single crystalline sample on the order of 1 μg. Generally speaking, sample rotation in transmission-type ESR measurement is quite difficult. However, high angle resolution Δθ(min)∼0.2° and compact design of our stage allow in situ sample rotation in strong magnetic fields at low temperatures. As a result, a systematic study of ESR spectra for different field orientations can be easily obtained without sample extraction from a cryostat. As an example, angle-dependent ESR study of Co Tutton salt in the millimeter wave region is demonstrated at liquid helium temperature.
